If you are a collector Casino Playing Cards you may have noticed the new changes in the packaging, numbering of Gemaco Casino Cards

New Packaging

New Serial Number on the Ace of Spades
I need to find out if this is a date code like USPC uses on their cards of if the serial number just corresponds to an order or a property.
You can tell from the ace of spades that this is a Tech Art II type of playing card - Hint... the small logo in the corners.

Below is the current style of Gemaco Card that our property is testing for 30 days.
