Made in China
They seem to perform about as well as an inexpensive deck from China usually performs - so-so at best.
That rough edge you commented on? It's definitely in the cut method. Many factories using cheaper processes will cut the cards into strips, cut the strips into rectangles, then push the rectangles through a cutting die several cards (even a few decks) at a time, sorting them out later into packs. It's that several-cards-at-once cut that creates those rough edges. USPC, on the other hand, will cut the sheet into strips, then punch the cards from the strips one at a time on the same die, ensuring smoother, identical cuts throughout the deck, and collating as they go. The process costs more in terms of machinery, and they use it because in the US, machinery is cheaper than manpower in the long run - the opposite is often true in many Asian factories.
Occasionally, particularly with decks from the transition period between Cincinnati and Erlanger, ended up with bad cuts probably owing more to an old die not being properly maintained. Dan and Dave's solution was simply to hold the entire pack in one hand and rub the edges against a piece of denim, such as the pant leg of a pair of jeans one might be wearing. It works pretty well. Maybe it will work on these Platinum Plus cards as well?
