A dime is composed of a steel core plated with copper and a nickel. It is possible that some sort of environmental damage has exposed the copper plating. Hard to tell from photo supplied. Whatever the cause, it would have happened after it left the mint so it would be considered PMD
Possibly the top nickel layer has been removed exposing the underlying copper layer. However it happened, it didn't look like this when it left the mint so it is some sort of damage however it was caused.
It's just wear. May have spent an hour or 2 as a Dryer Coin.
