Private Signings was designed as a cut-across program that will allow Paniniamerica to include more hard-signed cards in each product. They were sent out at once, and Paniniamerica ha've been including them in products as they've been returned. Naturally, the print runs vary, with SPs being about 1/4 the run of the common auto, SSP's about half of that, and XSPs being half (or less) of SSPs. There is also a 1/1 Platinum version of every card.
