[Buythatcard]

Look for the 1952 Topps Johnny Sain card with the wrong bio on the back. If it has Joe Page's bio, then that's the card.

I once bought a bunch of 1952 Topps commons which included the Johnny Sain card. At the time, I knew nothing about the wrong bio version. I later sold each card individually on eBay. Before I sell a card I usually research it to see if its a rookie or anything else. I was pretty shocked when I saw that I had the error version of the card.

It was a raw card (which I should have graded) but it sold for $265 back in 2009.

I think that makes a lot of sense that you are doing your research before sending the cards out to be graded. Good luck!
