The Studs are definitely rare - they transitioned from this box to the new one a little while back, I think even before the switch from Ohio to Kentucky. The Stud decks are an exclusive deck made for the Walgreen's pharmacy chain by USPC; that chain is the only place to buy them at retail as opposed to in the after-market. In fact, the older Studs were made with brighter shades of red and blue on the backs in this version of the deck - the new ones are deeper, more like crimson and navy than red and blue.
Any USPC deck, especially Bikes, that says Cincinnati but has a BLACK seal could have been made in either Cincinnati OR Erlanger. The D&D Arrcos are "black seal" - these were REPRINTS of the original issue, although probably of Cincinnati manufacture. Your "blue seal" Arrcos are the original issue, the real deal.
EDIT: the Arrco deck is original issue, but is also recent original issue. The older stuff had deck seals that look a bit like postage stamps, with the rippled edge and the adhesive that had to be moistened instead of like the modern sticker seals. The REALLY old stuff doesn't have what we know as the current USPC seal at all - they had tax stamps, government-issued, with the company initials in rubber-stamp "canceling" the tax seal like how the post office cancels a stamp when it's used. I think they stopped using the "stamp seals" in the '70s or '80s - they were definitely gone by the '90s.
