But, if I've got a valuable antique that would be of interest to an auction, that is definitely where I go. The economics are different and I get more of the cash.
Side note aside, this baseball card discovery sounds spectacular. Honus Wagner in mint condition? Seriously?
I just wanted to point out that the Honus Wagner baseball card recently found in somebody's attic is not from the same baseball card series as the extremely rare Honus Wagner baseball card that collectors sometimes refer to as the "Holy Grail" of baseball cards. That extremely rare Wagner card is from the T-206 baseball card series. The Wagner card that was found in the attic is from a different baseball card series. Of course, this doesn't mean that it's not worth a lot of money, but just that it's not the same card.
