1998 D Quarter 0

 I found this quarter and would appreciate any help in determining whether it is a mint error coin and if so what type.

No error, this coin has been intentionally damaged.

Welcome to the Forum-

Agree

See these fairly often. Coin has been intentionally ground down making it a damaged coin with no value above face.

Good example of someone in their garage going to work on a coin for whatever reason.

To make flying saucers for a bad sci fi movie, it looks like.

I DID NOT DO THIS TO THE COIN AND IF YOU LOOK AT THE EAGLE THERE ARE ZERO FILE OR UNEVEN MARKS ITS SMOOTH AS GLASS ONLY IN THE EAGLES RELIFE PERFECTLY OUTLINED HOW COULD SOMEONE SAND OR GRIND DOWN THE EAGLES RELIFE SO PERFECTLY AND ALSO THE EDGES ARE GROUND EXACTLY THE SAME WIDTH AROUND THE COIN ON BOTH SIDES IM NOT DISAGREEING WITH YOUR ASSESMENT BUT PLEASE EXAMINE THE TAILS SIDE AND THE PERFECT OUTLINE WHERE THE EAGLES RELIFE IS MIRRIOR SMOOTH AND LOWER THAN ANYTHING ELSE ON THAT SIDE OF COIN AS WELL AS THE ONLY THING THAT IS THIS WAY. PLEASE REEXAMINE AND REPLY. Thank you for your time

Intentionally damaged for sure.  Only the person who did it can know for sure how it was done.  The minting process is a pretty simple, straightforward, well understood manufacturing process.  There is nowhere and no way this could happen during minting.  On the other hand there are unlimited ways a coin can be damaged.

The fact that there is a rim on only one side tells you it has been intentionally ground. There is no other way for this to happen.
