1955 Topps Mickey Mantle on PSA Pop Report?
 

Anyone know why there is a 1955 Topps Mickey Mantle on the PSA pop report? It's card #209 on the site and is a PSA 1. Just curious...

I would not be surprised if it was this card:

(I just checked, and it's now gone.) For the longest time, the 1961 Topps pop report included a single instance of 1961 Topps #603 Pittsburgh Pirates Team. That is a card that doesn't exist, and was clearly just a 1971 Topps #603 Pittsburgh Pirates Team card mistakenly entered into their system. The "1971" was accidentally typed in as "1961" and into the pop report the card went. I guarantee that is what's happening here. A simple error.

Or this one , number 203
