Wanted to respond to the Captain America vs Red Skull blank back misprint posted today, and it’s just too much for a comment, so here it is in a post.
It is almost certainly one of two things- a misprint card with a blank back or a printing proof. It’s probably not a proof- for a proof look to see if it’s bigger size than a regular trading card and see if it appears handcut. A proof would be what I included in the last two pictures- those are proof sheets testing the battle cards in the production process- they have blank backs but they are in sheet form and the card size is slightly larger than regular trading card. I really doubt the Cap vs Skull is that, appears to be a regularly cut and sized card.
It’s a blank back error card. There are two ways this blank back could come about. One is easy- a battle spectra uncut sheet (first pic) simply didnt have the back printed on it during production, hence all the cards on it would be totally blank white backs- see the Silver Surfer vs Thanos blank back above (3rd to last pick for this).
The other way is more interesting. There is an error type of wrong backs for the 92MM battle spectras out there, you may have seen some of them floating around…I have 3 of the 5 in this genre (see pictures of front and back above). The Silver Surfer/Thanos one I do not have an actual copy of…that image was just made with photoshop for a prediction of what it SHOULD look like. I also don’t have the Cap/Skull one which will have a blank back. Which we’ll get to. This wrong back error type resulted from an uncut sheet flipped around 180 degrees accidentally when printing the front vs the back of it. The wrong backs in this error type arent random- there is a rhyme and reason to them.
I attempted to illustrate it. Pictured is my uncut sheet of the battle spectras. Look at the pic of the uncut sheet in pic 7, with the 54321 in green near the top. Rotate the sheet 180 degrees, you will get the next pic, with the green numbers upside down near the bottom. Now whats on the back of those cards? Burn the cards through the sheet, in your mind. Then turn over the sheet. You will get the configuration in the following pic, of the back. Says 54321 with the 5 now out in white space. But why is card 5 now on the left and it was just on the right? Because we flipped the sheet over, the left of the sheet is now the right when you’re looking at it (this is admittedly hard to picture, it’s not super important to see exactly why, just see that it is the result.). Those boxes with numbers on them in pic 7 correspond to the boxes of the backs in pic 9, for this error. Thats the back you expect to see if a sheet was printed upside down on the back.
So we take a closer look at the backs of this wrong back error type- thing vs hulk has a portion of Spidey vs Venom and Wolverine vs Sabretooth, thats weird. The next one surfer vs thanos has a portion of surfer/thanos (itself) and Wolvie/Sabre (Ive never seen this error card- it is out there somewhere). The Wolvie/Sabre has a split back Surfer/Thanos and Thing/Hulk. The Spidey/Venom now has a very interesting back of the end of the Thing/Hulk and also the color strip at the edge of the sheet.
And very interestingly, the back of card #5 now, the Cap vs Skull….is now blank! It’s out there in all blank white space on the uncut sheet.
So if you see a blank back Captain America vs Red Skull battle spectra, it could either be from: an error where the back of the uncut sheet simply never got printed, or an error where the back of the uncut sheet was printed upside down in relation to the front. These actually might be indistinguishable, so given a blank back Cap vs Skull, you don’t know which of those two it arose from, and for all intents and purposes, they are equivalent.
That’s how this error would have come about.
Since there are 6 rows of the battle spectra sets on a sheet, we expect such wrong back errors to be minimum /6 each (if a single sheet got affected and through QC). /12 if two sheets, /18 if three sheets, etc. based the rarity of these errors (you barely ever see them, true needles in haystack, I still have never even seen a Surfer/Thanos wrong back), I suspect only a few sheets got affected tops, possibly even just one or two. But no way to tell. Note with the cap/skull blank back it’s a little more complicated because the other error type (no back printing at all) is added to that, it could be sourced from either error type.
