It is unknown exactly how many of the monster boxes traceable to Philadelphia (by serial number on the monster box) still remained in their mint-sealed, unopened state by the time that the FOI release was finally made known in 2017, but the vast majority of them had been opened by then, rendering their contents forever indistinguishable from the general population of 2015 West Point ASEs. It has been estimated that as few as just eleven monster boxes (5500 coins) remained unopened, with seals unbroken.
Nly these surviving UNOPENED monster boxes from Philadelphia were eligible to have their contents authenticated by PCGS/NGC/ANACS as "struck at the Philadelphia Mint" and "one of 79,640 struck" and slabbed with the "(P)" (implied-P) mintmark.
