I just spent a week organizing and hard-sleeving my modest childhood collection, which dates from 1972-76 (mainly). It had been boxed up for 40+ years, and while not really interested in selling ATM I looked at eBay to see which were the more valuable among them. Most aren't worth anything, obviously, especially the ones I wrote on or used for various games we'd play, but some were being offered at fairly impressive prices. However, there seemed to be a lot of eBay auctions/offers for even the high priced, supposely rare, ones, and I didn't notice any of those actually selling during the time I was looking at them.
I am a long-time collector of postcards, including some hockey ones, so I know how collectibles markets work, and how pricing can be disappointing sometimes (most times), but I was wondering what the state of the (older) hockey card market was like right now and whether there is a better way than looking on eBay to get a grasp of their typical selling prices these days.
