PCGS Coinfacts 1834 H10C (Proof)

Since the launch of PCGS CoinFacts™, we have been hard at work updating and expanding the site's information. Here's another recent example:

Ron Guth: Breen (1989) listed Proof examples of LM-4 and an enigmatic (and still unknown) variety with the obverse of LM-4 and a new reverse with a die defect on the right side of the first A in AMERICA and a crack through bases of CA to arrow. Breen claimed to have seen this on an example in the Smithsonian Institution, but John Dannreuther (2010) says there is no such coin.

Logan and McCloskey (1998) listed Proof citations only for LM-4.

The 1834 Proof Half Dime in the King of Siam set is a later add-on; the set was missing the Half Dime when it was discovered in 1962.
