where is the mint mark on a 1916 mercury dime

The mint mark on a 1916 Mercury dime is on the reverse side, near the bottom of the design, just to the right of the fasces and below the olive branch.

What to look for

• D means Denver.
• S means San Francisco.
• No mint mark means Philadelphia.

1916 note

A 1916 Mercury dime can be especially important because the 1916-D is a key date, and its mint mark is still found in that same reverse-side location.

Easy check

Turn the coin over and look near the lower-left area of the reverse rim, close to the fasces base.

TL;DR: On a 1916 Mercury dime, the mint mark is on the back , near the bottom right of the fasces.
