Brett Favre error card?

[jiw98]

Has anybody here heard of or know of a 1998 Upper Deck Super Powers S4 Favre error cards?
I was looking through some football cards today and found two of the Super Power cards in a pile. One of the cards has Super Power spelled out on the card with a gold foil, the other is missing the gold foil. I can't find any info about the card so I thought I would try here.
Thank you in advance for any help.

It may have an impression of where the foil should have been.

The foil is on a backing paper, and gets pressed in place with a heated die. Then the paper gets advanced for the next card. (Or sheet, or... )
If the foil/paper roll doesn't advance, there's no foil lined up to press and the card won't get foil. It will get an impression from the die.

If there's no impression, then it most likely never got the foil. A lot of cards with no foil or impression came from unfinished sheets that escaped the factory.
Or the machine fed two cards, and the foil pressing made them sort of stick together. (Very hard to prove)

Unless it's a known thing where a bunch were deliberately released with no foil, they're usually treated as misprints. Valueless to some varying value to player collectors. Favre would probably have some value as a misprint.

Thank you, Steve for the info.
