Sorry I don't quite understand what you're trying to say Don, could you clarify it a bit for me please in relation to finding them for sale somewhere
There have been known instances where T11 ordered new printings of old decks, didn't offer the new printings for sale on their site, but released them to dealers to sell in their stores. Two such instances would be the Black Stingers and the Propaganda decks. Newer versions are clearly marked as having been made in Erlanger, and not Cincinnati like the original printing was. For decks originally made in Erlanger, there's no way to know without careful scrutiny (on the off chance of changed copyright dates and/or other markings) whether you're holding a reprint or an original. The market has started adjusting for this. First-printing Propagandas and Black Stingers are getting a premium price while the second-printing versions of each are getting a discounted price.
The Centurions are old enough to have been made in Cincinnati on the first printing. Newer printings, should they exist, would be marked as made in Erlanger.
