1906 Liberty Head Half Eagle. JD-1, the only known dies. Rarity-5. Proof-65 (PCGS). CAC. A beautiful and rare Gem Proof example of the Motto Liberty Head half eagle design type. Dating to an era in which the Mint prepared Proof gold coinage with a universally brilliant finish, this piece was struck from dies that were obviously polished both in the field areas and in the recesses of the design elements. The result is a delightful semi-reflective finish overall with minimal contrast between the fields and design elements. Fully struck, as expected for a Proof, with vivid deep gold patina throughout.<p>The Philadelphia Mint struck 85 Proof half eagles in 1906, the penultimate Proof issue in this long-running series. John W. Dannreuther (2018) has identified only a single die pairing for this issue, and he estimates that 50 to 65 coins are extant in all grades. With most certified survivors confined to Proof-64 and lower grades, the opportunity to acquire this impressive Proof-65 is sure to be a fleeting one in todays highly competitive numismatic market. Strong bids are encouraged. From the Castle Pines Collection.
