I figured this would be of interest to many of you on the forum.
Last week, I found, and moments ago, lost, an auction for these cards. I did not have the cajones to spend more than I bid, even though the trio went below my estimated values (with the help of a few posters here) when graded. The damn 30% auction fees crushed my soul.
Anyway, the Steinfeldt with bat with a Lenox back has no copies at PSA/SGC/Beckett, and sites like T206resource list it as 'possibly exists, but unconfirmed.'
Well, I'd say it's confirmed to exist now. It was in the hands of a 'high end' British collector. And based on other auctions from the same collection this year, they had roughly 20% of the set and some other nice stuff.
Woe is me. But, at least I found something worthwhile.
