Mercury dimes have a pretty neat history. They were only made for a short time between 1916 and 1945. Interestingly, the design created by Adolph Weinman was that of a young Liberty and given the name Winged Liberty Head dime. However, the common name, the 'mercury dime', stemmed from the confusion of young Liberty with the Roman god Mercury. The backside depicts fasces (yes, I had to look that up!), which is a bound bundle of wooden rods that represents strength through unity, and olive branches which signify peace.
Makin' jewelry AND learning history. Best. job. ever.
