Have you ever seen a back like this 1962 Topps Spahn?
 

I found this 1962 Topps #312 "Spahn Shows No-Hit Form" and have never seen a back like this before.
Clearly it got the base color for the back, but missed the run of ink for the stats.
Have you seen any other 1962's like this?
Any idea of the value?
It's not a true "blank back", so what is it called?
Thanks!

Here's the front

Cool oddball error. It is just missing the black ink pass on the back. Cards like that sell in the $5-$10 range maybe a little more if you can find a Spahn collector that also collects error cards.

A spahn collector would love it. I would say it's worth double what the regular card in same condition is. There are ore of those blank/wrong back cards than you might think

Thanks Ben and David!
