The first '59 Fleer set I bought cost me $200. That was back in the early 1980s. I never thought I'd sell it, but then again, if someone wants to offer me $7,000......
It's funny that some of the stuff I bought back then is actually now worth less than I paid for it. Some of those boxed 8mm films that cost me $25 often go for less than that on Ebay.
