That there are a ton of people that have no clue about how to price them them (myself included
) Whereas with post-war, there are various price guides/eBay listings plus a more established history of what they go for...
For example, I was at the flea market the other day and a guy was selling cards, he was dead-sharp on knowing prices for post-war (actually way too high--he wanted like $10 for a VGEX '69 Marichal) but when it came to pre-war he had a flat price on everything $35 for any T206 (all ranged from GD-VGEX) and $75 for any HOFer (Chance--or was it Evers?, Clarke, and some three-fingered guy...).
He also had NO CLUE about backs. I asked "Do you have any drum backs?" and he thought "Drumback" was a certain card/brand, i.e. he didn't realize the T206s could be worth much more if a different back. Unfortunately, he only had Piedmonts, Sweet Caps, Polars, and Honest...
Anyway, I guess the point of my thread is to say that there is a lot more misunderstanding/lack of information with prewar stuff than postwar, and that makes it even more intriquing...Oh well, that is the point of my thread, any comments would be appreciated...
