While 1940 proof Mercury dimes are scarce, they are not so to the same degree of rarity as the first proof issues debuting for the series in 1936. About 10,000 examples are known to survive, and most of those are in the PR64-PR67 range. Examples grading above PR67 are extremely rare, and virtually none are known with any substantive cameo frosting. Be wary of any cameo effect evident, as this is most likely doctored.
Obverse Description
Winged Liberty, or Mercury (the Roman god of commerce), is depicted facing left with LIBERTY spelled around the periphery. IN GOD WE TRUST appears left of the neck and the date is positioned just below the bust around 5 o'clock. The designer's initials "AW" appear to the right of the neck.
Reverse Description
A large torch is centered vertically adorned with an axe head and olive branches. UNITED STATES OF AMERICAN * ONE DIME * is spelled out around the periphery.
