Mint Mark Indentation

Noticed this on a silver bicentennial quarter (business strike)...



Even though it is clearly noticeable in the photo, it actually looks more indented in hand.

Whoever punched that MM musta been buff.

 

No wonder that's a filled mm. It should of went straight through the coin to the rev.

 

I see that sometimes on clad half dollars. Pretty cool, it looks whoever punched the mintmark on the die smashed that press on the die pretty hard.

 

Lovely dimple...........

 

Looks like my belly button after eating crackers in bed.

 

One of the authentication diagnostics of the 1932 D Washington is that the mint mark a lot of times looks to be sitting in a shallow crater. It's one if those diags that doest disqualify a 1932 D from being genuine if it's not present, but if the crater effect is present, then its a genuine piece.

that's funny and disturbing all at the same time.

 

If that were the case, the depression on the die would result in a raised area on the coin.

As you drive the punch deep into the die the metal has to go someplace. One of the places it goes is into a bulge around the punchmark. If the field isn't lapped down smooth again afterward, that bulge around the mintmark on the die creates a depression around it on the coin.
