Obviously T206 rare backs and variations have seen a huge increase in premiums over the past 10 years. I was wondering what the future holds for the rare variations from other (equally) popular sets. I'm talking mainly about World Wide Gum (Canadian Goudey), OPC (Canadian Topps) and Topps Venezuelan, but I'm sure there are others. I personally collect WWG and Topps Venezuelan because I appreciate the scarcity and love their more common counterparts to begin with. I've also found them to be undervalued; WWG is cheaper in a lot of cases. Plus who doesn't love reading awkward French translations about baseball?
Anyway, what do you think the future holds for these sets? Will they ever catch on as rare backs did in the T206 set?
Here are a few WWG's from my PC:
