I'm just going to come out and say it -- I don't have the foggiest idea where to price this card. For those familiar with the W502 set, you know how difficult the Two Bagger, Three Bagger, and Home Run backs are to find. They were all redeemable for prizes to very few stayed out on the wild.
To the best of my research, this is only the second Gehrig Three Bagger card known to exist. At the same time, no one seems to be actively hunting these variations down because they so rarely appear for sale. But this definitely has to make any list of Gehrigs rarest cards.
Price is:
PENDING There's a blank-back PSA 3 on eBay for $3k but it's yepbg, so, you know.
If you're an interested party, feel free to reach out. Thanks for looking!
