If you read the title of this article, you might think this was a typo---no $10 notes produced for circulation have ever reached anywhere near the Y block. However, in 2000, the BEP produced exactly that---to commemorate the new millenium. Series 1995 $10 bills and Series 1999 $10 bills were involved in the collectors' set, which was set at a minimum of 1,999 bills from each FRB. Therefore, 23,988 bills of each type, small head and large head, were printed exclusively for these sets. The bills were printed at Washington, were packaged in green boxes, and had serial numbers far above the final production for those years (1995 $10s never got further than the E block, and 1999 $10s didn't make it past block letter C.) The bills were sold in groups of 12, one for each district. They have sold for over $300 in recent years, with sets of both 1995 and 1999 bills fetching over $1,000. The success of this set paved the way for future premium items, like the 2003 $2 Premium Federal Reserve Star Set, containing low-numbered $2 star notes from each FRB district in Series 2003 (which was composed entirely of Minneapolis FRB notes for circulation), the 8888xxxx bills sold on the start of the Chinese Lunar Year, and, more recently, the premium sets of 2003A $2 bills with starting serial numbers 2008xxxx through 2011xxxx.
