Roosevelt Dime ~ Anomaly ?

[synoptic12]

I'm seeking some assistance here in trying to identify the cause of the anomaly on the 'Reverse' of the Roosevelt dime. I know there is an abundance of expertise here, in the many experts being in the numismatic arena. All professional replies are welcome. Thank you very much.

First, that's a Roosevelt Dime, not a "liberty dime."

 

Second, the reverse appears to have been machined flat. It doesn't look like a mint made error to me - it looks like post mint damage.

PMD (post mint damage)

It is abrasion. Put a dime on a concrete sidewalk, step on it and slide it along.

Surely, misrepresentation on our part which has been corrected. Thank you for your input.

Yes, that may stand to reason. However, not all surfaces are flat as the signature remains largely intact with minor abrasions.
