Welcome to the forum!
First of all, let me say I love these drums!
Your set looks good. Based upon the pictures in your album, you've got a set that is made up of pieces from different eras. The main part of the set appears to be a late 70s Wood-fiberglass set, based upon the hardware and badges. The extra toms, based upon the badges, are early 80s, and I can't tell from the pics if they're fiberglass or maple. By this time frame Pearl had discontinued its wood-fiberglass line.
As for the stands, the hihat is out of the 70s, but that BD pedal is late 80s or possibly even early 90s.
Now, as for value, well that depends a lot upon what someone is looking for and what they're willing to pay. I've attached a couple of photos of 70s Pearl Wood-fiberglass sets I've sold over the last 2 weeks. The one on the left sold on eBay through a Buy-it-Now for $479.99 (price included shipping) just about 4 hours after I posted it. It was pretty much "original" with only minor modifications on my part. I had listed it 2 or 3 times before at a higher price, and it set in a local music store on consignment at a higher price, but obviously I had to drop my price to move the set.
The second one is basically the same, only a re-wrap. The original wrap was shot, and what I re-wrapped it with was not an "original" type of wrap which no doubt devalued it. It brought $305 with only 2 bids ($299.99 starting bid, price included shipping).
I made good money on both sets, as I got them both pretty cheap -- which of course is what I look for when I'm buying. I guess I'm one of those nasty "low-ballers." :)
BTW -- What are the sizes of yours drums? The sets I sold were standard 14x22/15x16/9x13/8x12. The 14x24s and 16x18s always seem to bring more...
And, as I'm ready to post I see Mikey has beat me to the punch on the toms...
