I must say-
I've busted boxes of this product over the years, looking for the perfect Mike Schmidt card. It's a really tough set to find in top grade. There are a # of star and HOF cards from this set that do not have a PSA 10 graded yet.

Yes, the price is crazy. But I'm equally sure that you could bust boxes of this product, pay lots of money in submission fees, and not end up with (m)any 10s, much less one of this specific card
