Mint in box more than $20. Not lots more though is my guess. Hard to tell age. Maybe 1950's?

Thank you for the reply. They definitely seem old but there's no dates or anything anywhere on the box. Its just a gold box that holds both decks. the only number i saw is on the ace of hearts which has the company logo and a number (90.964) on the bottom but that's about it. I just thought it was interesting that it was the same images on the front as the tudor rose set I've seen pictures of online but the backs were completely different (if you google tudor rose piatnik you'll see the back are totally different). I thought maybe they were a bit more rare because i was unable to find any pictures or info on this specific version of the set.
