If you aren't a collector then even USD 50 can seem like a lot for 26 year old electronics. The vast majority of the world doesn't care, that's why you use eBay, you need to find the pocket of collectors and enthusiasts that DOES care....
A "flea" market is the worst place to sell collectables.
I don't know what the deal is. I just saw 2 working A1000s in a Baltimore (Glen Burnie) flea market for $100.00 each with original box, keyboards and mice (and the 256K RAM add on). They were both in great shape, and the seller had them running demos at his stall. People were trying get them for $50.00 or less....
