I’m no expert, but this appears to be an OLD deck, complete except jokers AND the box – A total steal!
This one made me pull out The Hochman Encyclopedia Of American Playing Cards to see what the ace was all about. As it turns out the deck and/or ace appears to be from the 1880’s and was first published by the New York Consolidated Card Company. According to Hochman there were at least three diffrent versions of this brand “Triton”. This specific Ace appears to be the NY51B according but please veroify this yourself on page 59 of the encyclopedia.
