As shocking as you might find it, Rainey, back in the '90s I actually sold several pieces of my extra DS stuff on eBay - duplicate sets of the pink and green card sets (which netted me $400 and $350, respectively), a duplicate set of the 1897 posters ($225), a set of 30 of the Ross novels ($180), a few items from the 1968 DS fan club - the book cover, a sheet of Barnabas stamps, and a calendar ($150), the empty boxes for the pink and green card sets ($100), a set of Quentin postcards ($70), and a set of wrappers from the pink, green and 1897 poster sets ($60). All told, a nifty sum of $1,535 - about a 5,280% profit!! (It paid nicely to get in before the current glut of DS merchandise became available on eBay.
)
No home-visits or affidavits of good character were required.
But I would NEVER sell anything that wasn't a duplicate of something that I already had.
