I had an 11 piece in the same finish and similar sizes that I recently sold off. Mine was not in nearly as good of shape as this one. Mine had a mix of modular and clip style mounts as that is the way they came for the original owner. 26, 24, 20, 18, 16, 15, 14, 13, 12, 10, 14x8 Coliseum snare.
I tried selling the kit as a whole, but was not geting offers. I ended up selling the 20" and snare separately and split the remaining drums into 2 kits. I can't remember how much I got total as I ended up selling it over a period of several months, but I think I ended up getting around $1800-1900 total for everything.
If mine looked like yours, I would have kept it.
You may want to sell the cymbals separately.
