I agree that you should try and list them here and if no-one is interested then you probably would sell them on ebay; theres loads of stuff on there now, varying from auctions of one software title to A1200 with accessories, printer and software, from 99p upwards! And nearly EVERYTHING listed that is Amiga related has at least one bid, so will be sold. Thats just ebay UK, so the American version probably has even more.
The one thing to remember is that you have pay ebay fees so you have to take this into account when selling; I know your not interested in making mega-moolah but you don't want to have to pay for people to help you do a clear-out!!!
