Digimon Digital Card Battle had different card backs between the american and japanese versions of Digimon Digital Card Battle, which also applied to the physical card game at the time.

The card backs were unchanged in the english dub of Digimon Tamers, which is also true for Digimon World 3 (in spite of the card game in Digimon World 3 not actually being the same one).

Oddly the english version of Digimon Rumble Arena, which was mostly based on Digimon Tamers, had the american card game backs in the american version instead.
