The Goodwill stores in my area have a special thing they do for the items that they feel are above the typical standard....
They set up a special display, with locked cases, usually, and have a bidding book...... they take bids for a specified number of days, and the high bidder gets to buy the item.
I've seen a lot of stuff in there... antiques, collectibles, musical instruments, better electronics, anything they feel is above the rest.
We also have a local organization called "The Caring Place" that is similar, in that they have a thrift shop/resale store with a couple of specialized areas. The nicer items go in those special shops... they also put things on Ebay and get better prices that way, also. All of the money goes to support their programs, which includes a food pantry, social workers to assist clients with different things, parenting/budgeting classes, and is in general, a resource for low income people. With The Caring Place, all the money stays local to our community.
