From O-Lugs

"Value" is decided upon by the individuals doing the deals. There is no real market price for vintage drums. The market is two guys in a bidding war one day and fifty guys the next day so there really is no way to quantify such an inconsistent demand...Okay....according to eBay pricing, the average price that a vintage SC shell pack in a "common" color goes for is, let's say...$1K (just to keep the math easy). That could mean that the trend is that all vintage SC's sell for $1K....OR....it could also mean that one SC sells for $500 and another one sells for $1500. So, my point is: "How do you determine "over/under" valuation? A Super Classic in gold sparkle is one thing. A Super Classic in Citrus Mod is quite another thing to a collector. Sound-wise, they are the same.

Well you ask a statistician and he will tell you to collect data and analyze it. Which is what I've done in my study of Paiste 602/Sound Creations since 2006. I capture all the completed sales on eBay and others as I hear about them. 1850 sales and counting... raw data free on request.

I fit statistical models which take condition and rareness into account, and I use robust estimators (trimmed means or medians) so they are not over-influenced by extreme values. This gives you expected values (or better: expected ranges) which do answer questions about "expected value".

Now you make arguments about eBay no longer being a useful place to collect data for vintage drums. Of course in order to evaluate your argument (being a statistician :D) I'd like to see your data on this. Have you been collecting data over the years and can you demonstrate that the proportion of "duds" on eBay has changed compared to the whole market? I know that eBay isn't a representative sample of the whole market but I haven't had data to quantify the sampling bias effect. Do you? I'd love to improve our collective understanding of this phenomenon.

From O-Lugs

Here's a good one: Can anyone tell me what the current value of a vintage Ludwig Jazzette kit is? Well, on eBay, there was just one sold to an overseas buyer for around $1800. Does that seem like a good deal? Okay, well there's a website that had a nice Jazzette listed for $3500 and it sold right away. Good deal? Okay, there is an overseas buyer who has a standing offer to me for $9K for my '69 Jazzette. Ridiculous! you say? Maybe. I still have the kit. So, I ask again (rhetorically)...Can anyone tell me the current value? I see three different current prices. Which one is "right"? Answer: The one you're willing to pay. :Santa:

Well, they are all "right" and they are data points not the answer to the "expected value" question. And anybody who gives a simple point value rather than a range (which is evidence based not off the top of your head) isn't doing the job properly. Best practice for many decades calls for somebody to report an "expected value" with a disclosure of uncertainty attached (a range of variation, or whatever).

Since you asked me what price to expect, I'd give the usual statistician cautions (you get what you get on the day, prices are highly variable, eBay isn't a full reflection of the market, etc) and the data:

And leave you to it. If I wanted to devote more time to it I could fit some robust statistical models, but the data should do.

Sorry about the non-tabular formatting but vBulletin doesn't support html tables. Also when I started on this project I wasn't recording as much detail as I do now. I can post the definitions of all the fields and codes as required, and of course the original spreadsheet is available free on request. Oh, and not absolutely every entry I record is a sale. Occasionally I record something as a placeholder and put 0 bids -- for example the classicvintagedrums online offer at $3995 isn't yet a sale (last I looked).

And to that most recent sale of a Jazzette (shown below). I was suprised that it lasted so long with a BIN of $1899. Because it went for a BIN (possibly low but we can discuss that separately) it doesn't contribute as much to an understanding of price expectation because it simply offers a lower bound. "Somebody thought it was worth greater than or equal to $1899" rather than "somebody thought it was worth $1899".

I think the snare (certainly highly desirable if a 4x14) looks more 3x13 than as advertised a 4x14. A 3x13 jazz combo is still desirable...but I worry about that part of the finish I see. Refinished or original? I'd value other opinions. My old eyes and lack of experience keep me from seeing everything you guys do. Still, I'm not surprised that this went for $1899.

With my Paiste study (where my analysis is really focused) I've seen prices for 3 seemingly identical cymbals go for $95 on day, $127 the next and a rogue one for $250. I'd see this as similar to your pondering how to deal with lots of price variability. Am I worried by that? No, of course not. Statisticians have been dealing with this sort of variability for many decades. Collect data, analyze, publish results and raw data so others can spot room for improvement, update, repeat. The virtuous cycle of science. Yes Sir

As to Istanbul made K Zildjians. I don't collect or analyze any price data on them because I treat that as Drumaholic's exclusive province.

WOW! heh heh heh VERY impressive!

I can only respond by saying this. I have collected data in my own "magic-based" way and have determined a plethora of charlatan Jazzette monikers out there. So, when it comes to complete and original Jazzette drum kits, I guess I could throw out about 99% (just a guess based on magic) of those listed due to the fact that so many of them are "tampered" with, rewrapped, NOT really Jazzettes, NOT complete kits, NOT matched kits, just the bass drum, etc. In which case, IF I did that, I would have a much narrower field to average. Your terms only account for what anyone is calling a Jazzette and not the true kit, itself. In fact, there might not even be one legitimate Jazzette kit on that entire list. The mahogany Jazzette that sold for 1899 on a BIN was a real Jazzette shell pack, however poorly the finish had flaked off or not and, to the people who know real Jazzettes, it was a steal at that price. So, yeah, I'm not surprised to see it go for that price, either! ;) I wanted to buy it, myself, but my vintage drum budget is spent and gone for a long, long time. Whoever got it is a very lucky person. Still, that snare drum was not matched. The only Jazzette I have seen with factory matched Supra and it's original hardware package, to date, is my '69. And, until I see another one that's more complete, mine is going to remain at the extreme high-end for Jazzettes. Who says? I do!....for now.:Santa:

Statistical information is only as good as the legitimacy of the input. If what is input into the calculations is not correct or relevant, then the output is neither correct nor relevant.....

....That's where magical information comes in!DOH

Excellent post above, Zenstat. I have had a minimal amount of statistics in college, (I minored in Economics) and would be curious as to what statistics formula you would devise to come up with a price range for a Jazzette set. A simple glance at all the jazzette sets and their prices, I'm actually struck by how consistent they are, not how inconsistent they are. But I'm not a human calculator or a statistician. Still, I think I enjoyed reading through that list of data more than reading any of the prior posts on this topic ;)

Believe me, when it comes to legitimate Jazzette kits, there's almost always "something" about them. Out of all those statistics, only a fraction is actually applicable to the question of evaluating an average price to expect to pay for one. But then again, there are a few kits on that list that would need further research in order to determine their legitimacy.

Pounder,

Let me ask you this:

If I call a 12/14/22 a Jazzette kit, then is it a Jazzette kit?

If you answer "yes" then the discussion is over.

If you answer "no", then why would you ever, in a million years, think that the information compiled on that list is any more relevant than my statement that a 12/14/22 is a Jazzette? Almost every single one of those citations is basically irrelevant because they have little or nothing to do with complete and correct Jazzette kits.

See, if people can throw around that term at will, then it can mean anything to anyone at any time, can't it? That list takes into consideration too many incorrect terms.

Define the terms BEFORE you consider the averages is all I'm asking.

O-lugs: Thank you for bolding my list to show the reasonable level of accuracy I have when recording "issues" with the drums for sale. Lots of typing there. Isn't it nice to have evidence to work from to make a point rather than use magic methods? I don't think I let any 22 size kicks sneak in there. Did I?

Of course I don't use all this data to asses the expected price of pristine all factory original museum quality Jazzettes. But it is very useful for assessing several things. Here's a list off the top of my head:

[list]

prices for flawed Jazzettes (interesting in its own right) going for $1800 - $2200 with exceptions

[*]the proportion of flawed Jazzettes (high)

[*]the proportion of inaccurate descriptions (high)

[*]creating a list of things to watch out for in descriptions (which might help both buyers and sellers do a better job)

[*]a lower bound for what nicer Jazzettes might fetch (greater than $3500 in today's market)

[/list]

I don't feel bad about contributing to any of these ventures.

...would be curious as to what statistics formula you would devise to come up with a price range for a Jazzette set. A simple glance at all the jazzette sets and their prices, I'm actually struck by how consistent they are, not how inconsistent they are.

I mentioned medians and trimmed means earlier, as preferred estimates of expected price. With the Jazzette data I've given I wouldn't use anything other than the data I've presented. It requires reading and thinking about all the different "flaws" of the sets, not a simple calculation. There isn't enough data such that presenting it all gets out of hand for those who are interested.

In terms of my decades of professional research, to establish a range I might use the 95% confidence interval for the median (yes they have confidence limits like means) or some other robust estimator. I tend to like the whole robust estimation approach. But if you want something you can do easily in a spreadsheet just sort the data. Then you can find the median and similar values easily by counting. You do need to filter out any data points which really shouldn't be there. For example, with my major research project (the Paiste 602s and Sound Creations) you need to filter out cracked ones because their value drops to $10-$50 where intact ones might fetch $150-$400. So you really don't want to include them (except in a specific analysis to find out how much their value drops! :D). Anyway, once sorted you can fill in these five values and that pretty much does it:

highest

half way median to highest

median

half way median to lowest

lowest

Most would sell in that center of the distribution (the two half way measures). A few will always sell at the extremes. Sometimes for obvious reasons of being mint or in poor condition, sometimes because there is just lots of variability.

I've got several textbooks on my shelf around the corner and I could probably look up the special names Tukey (or his followers) give to what I'm calling those "half way" points. But I'll just post this as is because it isn't really all that relevant to most people here (and since O-lugs apparently doesn't believe in evidence or statistics I should have warned him earlier not to waste time :D). Pounder: If you want to know a bit more about the whole area of robust stats give me a PM and I can hook you up. Might even be enough stuff in Wikipedia.

No 22's...but a couple 18 X 14's -which is essentially the same effect as a 22 when it comes to the Jazzette moniker.

The list is a nice list. As far as "evidence", I can reduce that down to 4 (possibly) legitimate Jazzette kits. When I was researching the Jazzette many years ago, myself, and I came across SO many illegitimate ones, I learned VERY quickly to disregard them at a glance. So as nice a list as it is, it's got a lot of "noise" in it that I filtered out.

From that list, here are the only kits that I would consider as legit for the term Jazzette KIT

1.) Jazzette 1969 maple finish $3,600.00 -1 eBay 8-Jul-08 poppy76 bought it

2.) Jazzette 12/14/12x18/14 1056741,1056743,14=1559039 3 ply wmp $1,400.00 -1 eBay 30-Oct-08

3.) Ludwig Jazzette 1969 maple $3,151.99 15 eBay 30-Nov-08

4.) Would be the mahogany one that just sold for $1899

I know the one Poppy got (#1) did not come with a matching snare drum. I don't know enough about (#2) to determine legitimacy, but I would be curious to learn more about it in order to consider it viable to average along with the others or not. The same goes for (#3), but that price indicates that other people who DO know what a Jazzette is were probably bidding against each other to get it for a good deal. (#4) was an outrageously-good deal, in my opinion -still, no matching snare drum.

Also, those prices reflected in three of the examples are 3 years old already. Those aforementioned Jazzette kits are now sold, too. That means there are that number fewer on the market for sale...which means the chances of finding one for sale are less than ever...which means they are that much rarer...which means the market-perception of their value may have changed accordingly, as well.

Pricing comes down to whether or not it's raining in Bulgaria or not. It has to do with how long the yak's hair grew this season. It's based on the color of the clouds or on the pattern of the Oyster Blue Pearl wrap. It's magic. Two people decide to make a deal. The deal gets made.

So you really don't want to include them (except in a specific analysis to find out how much their value drops! :D).

.....Exactly.......
