I would sell a few select pieces on eBay and donate the remainder to the co-op. I donate a pick up load to the co-op a few times a year, usually donor bikes, steel wheelsets, take off parts, etc. What they don't want is recycled.

If you sell hubs, MAKE SURE cups and cones are good first.

Realize your left over parts, sold on eBay, not only bring you some coin, but help someone else with a rebuild. I sold a 1987 University of Illinois yearbook, had been sitting in a box for at least 25 years, doing me no good. The buyer turned out to have a collection of U of I yearbooks, and this was the one year he was missing. So he was super pleased to get it, and I obviously did not need it. Win/win.

Last UO8 frameset I had went to the co-op.

And FWIW, some of the low end French bikes had Simplex QR levers, which can have good value.

If you want to be charitable, you can always donate cash from selling the items. Realize cash can be used to pay bills. I write checks to my favorite charities every year from proceeds of flips acquired from them. Its one complete circle.
