1993 Topps contains a handful of variations which I will outline in a later blog. But for now, take a look at one of the weirder ones: #96 featuring Mariners pitcher Russ Swan. The first version has the “Complete Major League Pitching Record” heading printed twice. The second corrected it and shifted it to the left as well. Though one can never be sure, I am almost certain that this is one of my own discoveries as it had previously not been mentioned as far as I know.

Which do you think is the scarcer of the two?
The double-heading version is definitely scarcer.
I also have the error card that your talking about, had not noticed until I read your blog, I also have a 1993 topps russ swan with the back of the card completly blank, what would these to cards be worth, and what is the rarity of the blank back
1993 Topps Blank Backs are pretty common. In fact, complete sets usually show up on ebay every few months. Usually stars and heavily-collected players sell for $1 or $2. Jeter sells for much more than that, though.
Do you happen to know how rare 1993 Topps Gold cards are that are missing the gold foil on the fronts? (Sorry, not related to the backs.) The indentations are there, but nothing but the white border and picture can be seen from afar. Seems like it could happen a lot, if they run out of gold when printing. Just curious. I have a few.
