Aquarius test set

[Ksdavis1126]

Hi I just resent bought a 1990 Donrus set and when I scan it on several apps it's coming up as Aquarius test card . However it's not stamped on any of the cards but every app all says same test set message ? Does any one know if it has to be stamped to be authentic

Aqueous test is a very rare version that is stamped across the back of each card. Very unlikely they are aqueous

Agreed - if you search ebay for 1990 Donruss Aqueous Test - you will see images that have all the card backs stamped with AQUEOUS TEST.
