Was there a 1943 Mercury dime made without a mint mark?

Answer 1

Mercury head dimes from 1940 to 1945 with or without mintmarks are all very common, especially in circulated grades. Most are valued just for the silver, as of today 10-13-11 it's $2.00. An uncirculated coin is $3.00-$4.00.

Answer 2

The "W" on the front is not a mint mark but, the designer's initial. If there is a mintmark, it will be on the back.

Answer 3

Yes, but all Mercury dimes have a W on the front, it's the initial of Adolph Weinman, the designer. Not the West Point mintmark. Mercury head dimes all have reverse mintmarks.

Answer 4

Yes - 191,710,000 of them, all from Philadelphia!

Remember that prior to 1979/80, Philadelphia coins except for "war nickels" never had mint marks.
