Four cards in 1994-95 Upper Deck Series One Hockey have variants. Cards of Mario Lemieux, Igor Larionov, Sergio Momesso and Mike Sillinger were produced with two different numbers on the back.

Below are pictures of each of the four cards’ fronts, plus pictures of both back variants. 

Mario Lemieux & Mike Sillinger

Lemieux (card #22) and Sillinger (card #200) had their numbers swapped. 

One version of the Mario Lemieux card has number 22 on the back.
The other version of the card has number 200 on the back. 

One version of the Mike Sillinger card has number 200 on the back. 
The other version of the card has number 22 on the back.

Igor Larionov & Sergio Momesso

Larionov (card #65) and Momesso (card #85) had their numbers swapped.

Originally, I thought one version of each card were errors because Beckett gives them the “ERR” designations in their online price guide. However, Upper Deck did not issue checklists that year, so whichever version is “right” is up to the individual collector. I might say that card #22 should be Mario Lemieux, and you might think card #22 should be Mike Sillinger. Since there is no checklist to check these against, we would both be right. 

Both versions of each card were reportedly printed in equal quantities. This is consistent with what I got when I opened a box of 1994-95 Upper Deck Series One Hockey back in 1994. I pulled three copies of each card — two of one version, and one of the other version. One version does not sell for a premium over the other version. 

My guess is that one printing plate — or sheet or whatever Upper Deck used for production back then — had different numbers for these four cards than what was on the other printing plate. (I believe that Upper Deck would have had multiple plates to print more cards at once.)

Note that each of this numbering variation also carried over to the Electric Ice Parallel versions of each card. So all you Mario Lemieux collectors — or Sergio Momesso collectors, I guess — have four versions of the card to track down. ■
