1982 D Quarter With T Error On Face

If that is the only device seen, it is probably not a die issue (as the dies are incuse on that area and leaves that area raised) if the 'T' is incuse, then it would be coin damage. Also nothing during the die creation process would cause a single device. If it were a double striking error, the rest of the die devices would leave other devices present. So to have a single device present, it is probably damage to the coin. But images would help us see what you see on your coin.

Dose not look like damage it's to clean

So no value?

is the T on the face raised or sunk in?

The devices on the edges of coins on dollars are incuse. They put one on the edge and altered then hit the coin with a hammer and raised a 'T' on the head. I figured someday someone would do this, and I had that solution figured out years ago when they started the incuse devices on the edge. Now we see one.

For what's it worth, might be wise to post a couple more photos of the area of interest taken from different angles--not too close in. Thanks.
