Coin and Paper Money Collecting/W mint marks ?


I have a mercury dime and a walking liberty both uncirculated but with the "w" mint mark. Does this make the coin less valuable since its not p d or s?

Hi Joey,

Assuming you are seeing this "w" on the front of the dime, and the back of the half, this is not the mintmark, but actually the designor's initials.  Adolph Weinman designed both coins, and that is actually a monogram of his "A W" initials.

here's a close-up of the obverse of the dime, showing the "A W" monogram :

here's a close-up of the reverse of the dime, showing the "D" mintmark at the bottom, just to the right of the word "ONE" :

here's a close-up of the reverse of the half, showing the "S" mintmark to the left of "HALF DOLLAR" and the "A W" monogram to the right :

if you don't find a "D" or "S" mintmark on these coins, this implies that the coin was struck at the main mint in Philadelphia.  At the time these coins were made, only the "D' and "S" branch mints got an actual mintmark on them.

I hope this helps,

My strong familiarity with all U.S. Mint coins, extensive reference library, and close relationships with many other dealers allows me to identify just about any coin made in the USA. I receive regular updates to all the current price guides -- both wholesale & retail -- to provide accurate values. So, with a good description or pictures, I should be able to identify and value any U.S. coin you have.


I've been a coin dealer since the 1980's and a coin collector since the 1960's. I specialize in U.S. Silver Coins and have an active online website -- The Working Man's Rare Coins -- -- offering information and inventory in U.S. coins.
