Dear henryjames,
Welcome to the forum. Your "S" mint mark spot can be interpreted in several ways. Are you looking for 1 or 2 openings per design to hold the clad and silver proofs? That exists, as 1 "S" hole from Whitman Publishing in addition to the P/D coins. Littleton, Dansco among others, offer 2 "S" openings for both proof coins, in addition to the P/D coins. That would explain it all, only the Mint decided to offer this year only so far, "S" mint circulation quarters that is sold as numismatic items, as part of the "75th Anniversary" of the current SF mint building. To the best of my knowledge, no album manufacturer has offered a revamp of their current ATB albums or a supplementary page to hold the five extra quarters. Presumably they are waiting to see if these S quarters make a reappearance in 2013.
