I don't know if you know who compiled your collection.
I will say, that I have run across a great many assortments such as the one you have in flea markets and garage sales, that the sellers claimed they did not know anything about. Often-times, guys who run-up collections such as
yours will buy a new part, unsure if it will fix the problem they have. If it doesn't fix the problem, they will assume the
part they just removed is good, and save it in their parts collection stash.
I'd look at some of the components and see if they are actually new parts, Not a lot of people will want used/unknown parts. If the parts are actually new, you don't know what they are, have no use for them, and want to
sell them: you can list them on eBay or Craigslist, or some other site like that. If you show a picture, a part-count, and a starting price on eBay, let the buyers bid on your collection until you get the highest price you can for them.
In answer to your question: somebody will want them if they are new and unused.
