I have a bunch of old books starting with 1878-1934, and nobody will buy them unless they are in perfect condition; and, let's fact it, how many old books like that are in mint condition.
Same thing the antique and art dealers tell me: during this Recession, antiques have to be in mint condition to bring any money.
When times are good, buyers aren't so picky as now. If you have anything and don't desperately need the money, I'd hang on to it until this market turns around, frankly.
However, if I can get an old brass bed frame during these down times I'm grabbing it. I always wanted an old brass bed, so I can feel like I'm one of the saloon girls in the old cowboy days. You can call me Miss Orchidflower if you want then....
