I recently became aware that there was another minor variation in the high number Upper Deck card from 1990, similar to the 1989 Topps rookie card. You have to look closely to find it.
I don't blame you.
It is is in the position. The "C" on the variation is off-center somewhat. There are enough of them out there to know that this was somewhat common. It is not the most exciting error card in the world, but there is a precedent for cards like this bringing in a premium. I am not saying this is a high-dollar card by any stretch. But it is an interesting thing to have.
