What are your experiences with older holders in GC auctions
I see many OGH rattlers and generation 2 OGH holders offered regularly in Great Collections Auctions non CAC. Do you find generally that these coins submitted by collectors and dealers are picked over. Can you find real upgrades or are they a rare exception. What have you learned by buying these coins. Overgraded problem coins, correctly graded nice coins or a good amount of undergraded coins?
