The Mint does not print currency, that responsibility falls to the Bureau of Engraving and Printing. The BEP does sell uncut currency but they do not sell only two notes, the smallest partial sheet is 4 notes. The 99XXXXXX serial number denotes an uncut sheet as those high serial numbers are reserved for that purpose. Unfortunately, the seller cut up either a full or partial sheet to get two notes
