On the D, you see the bottom of the 1 sticking out a little under the 2. Sometimes you see the pointed top of the 1 at the tip of the 2. It's not as obvious as the Philadelphia overdate, except the doubling on the 4 is quite easy to see.
Every once in awhile I’ll grab a roll of mercury dimes if I see a decent price. Found one of my last 2 holes. Looks like some damage on the bottom of the reverse… but it’ll still go in the album.
Nice coins @ernie11. @paddyman98, Thats why NY is out of dimes, you should be arrested. Just kidding congrats!
