Ron Guth:
The 1805 Half Dime has the second lowest mintage of the Draped Bust, Heraldic Eagle Reverse type, making it a very difficult coin to locate in any grade. Nonetheless, the Condition Census consists almost entirely of About Uncirculated examples, with the exception of one Mint State piece - a lovely, high-grade example estimated by PCGS to grade MS64.
Like most examples of this type, the 1805 Half Dime is usually weak at the tip of the bust and in the corresponding area on the reverse of the coin (upper right). Adjustment marks are rarely seen.
Only one die marriage is known for this year (LM-1).
