Probably a grease-filled die.

Disagree, that is not a greasy (oil) die fill but caused by friction. Oil filled dies give a smooth surface. Similar friction has worn the 6 (the date often suffered in coin rolls). Perhaps it happened in a bag of mint coins where the rim of another coin was rubbing against the D such as might occur to cause bagging, if the bag was subject to constant motion back and forth (think of a train carrying bags of coins being distributed) then one point (the D in this case) would really cop it.

A grease-filled device doesn't have to be smooth. If the D was removed by rubbing in a bag, it would have required a LOT of rubbing, and the other devices wouldn't be in such nice shape.

I think Neal is on the right track but for what ever reason it looks to me like its been ground away with a Jewelers wheel esp. in the 3rd Pic.

I suppose that's a possibility. Why would someone remove one letter, though?

I'm working on the assumption that the damage isn't down to someone playing silly buggers (like a jewellers wheel) as there is nothing to be gained by that PMD. If the point of contact with another coin was at the D then all the wear/damage would be concentrated at that point. If that isn't how the damage happened then what other (rational) reason is there? |

It may not be the result of someone playing 'silly buggers', but it does seem likely. |

In my opinion it is a filled die. Whether it is grease or oil is any question. To me it seems like some other form of "Mint Debris" has blocked the D.

It looks lie the "D" was removed from the coin. PMD |

I agree with Airgem, Die Fill , if it were ground or sanded or removed in any way there would be other obvious damage .
