My educated guess would be they are among the least valuable of the Golden Nugget decks. Think about it - this is like v5 S&M; compare that to the four previous versions in price... But that doesn't mean they're valueless; a lot of people love casino decks, and uncanceled decks are even more sought-after by some, especially if they were a table-used design.
There is indeed another recent post about these decks - look harder next time! But that topic did deal more with whether or not it was a fake deck, while here you want to know rarity and value.
