I know nothing about the W coins, but I have acquired two dimes with it. Please inform me whether they have any value at all.
That's not a Mint Mark.. It's the Designers Initials. I believe it's W for Weinman https://en.m.wikipedia.org/wiki/Mercury_dime Yes Adolph.. Thanks Tommy
Adolf Weinman to be exact. paddy is correct. The W mintmark you may have heard of was on the Roosevelt dime and was for West Point.
Correct. Here is mine - https://www.cointalk.com/threads/10c-1996-west-point-mint-ms-67-ft-ngc-10.292192/
Yes. The mint mark on ‘mercury’ dimes is on the bottom left of the reverse. Both of your coins have ‘D’ mint marks for the Denver mint. Note: dimes minted in Philadelphia had no mint mark until the early 1980s.
Or to put it another way, since the early 1980's, all Philadelphia-made dimes have been "P"ed on. Either is believable.
