EBay, Collectors, Flea Market & Antiques

I'm not in the resale business but must downsize what I have and prepare for a move if I can find an affordable apartment. I will lose my shirt under any circumstance since my late husband and I furnished our house with formal, some antique furniture in the 1970's and 1980's..
In my neck of the woods, what you paid ,..say...$2000 for an inlaid dining room table would probably sell for $200. There you are! I would take a big loss and have to pay taxes on it if I sold other furniture and antique items.
Like many others, we will have to pay a tax. My stuff..mostly formal mahogany period and Centennial furniture has no market now. I don't even count the collectibles that I'd be lucky to find someone to pay anything for.
Take into consideration that I(and others) have no receipts. Who saves old receipts?
Meanwhile, the rich get richer...I won't post my thoughts on that subject.
