Not sure if this is a variation or it just missed a step being made
 

Need some help with this card. Not sure if this is considered a print variation or just a card that missed a certain step of the process when being made (like missed a certain color of the stamping process).

But I found this checklist with Checklist in red today in a random notebook at my LCS. They had regular one (the yellow print) right next to it. As I said, not sure if it's a print variation or it just missed a step in the process of being made.

But I'd like to know so I can catalogue/list it properly. Thanks.

There are three variations on this one, checklist on front in yellow and 98 in black circle on back, checklist on front in yellow and 98 in white circle on back, checklist on front in red.
