E120 SGC Rejection: Blank Back or Missing Back?

[HOF_Forever]

Hi all,

I'd like to consult with the experts who are more knowledgeable than myself. I'm not really into caramel cards but decided to buy an E120 Dave Bancroft for my "one card of every HOFer" collection as I think it's a cool looking card and I like that it reads Dave (Beauty) Bancroft.

I bought a raw E120 Dave Bancroft at the National from a reputable dealer. It was marked as a Blank Back. My perfunctory research shows that there are blank back E120s and they are more rare than the normal back. I paid a bit of a premium over the regular back price for the card but nothing crazy.

I decided to have the card graded by SGC as I was dropping some other cards off with them. They hit me with a NO - CANNOT/DO NOT GRADE on the card. I emailed to ask why and was provided the following response:

"The reason is that the back of the card is completely missing. Due to this, our team is unable to properly authenticate the card in its current condition. I apologize for any inconvenience this may cause."

To my eyes the back looks fine. No glue, no missing material, or evidence of being in a scrapbook. There a small crease on the top right of the front that goes through to the top left of the back. To add to the mystery, the front of the card has green printing. For some reason I can't get a clean scan of the front, but I assure you, it's the normal green. If I'm allowed to post a cell phone pic of the front I will but I believe all images still need to be scans.

What does everyone think? Is this actually a blank back or was it mislabeled by the dealer and cleaned so much the type was removed?
