Variety Equivalents:
Breen 6460, Breen 1-B, PCGS 8107

Notes:
The 1810 Large Date, Small 5 is an extremely rare coin.  Breen cited "fewer than 6 seen, none UNC".  The PCGS Population Report lists only one example of this variety, a single MS-63, but this was a mis-attributed Large Date, Large 5 that appeared as Lot 1455 in Early American History Auction, Inc.'s Mail Bid Sale of April 22, 2000!
