Grease Fill & coin damage on a coin enlarge the devices on a coin The
Grease Fill prevents the lowest part of the die will prevent the tops of the narrow part of a device to be formed. A coin that is damaged will make the highest part of the devices to be altered by contact or flattening. But for a device to be reduced, then the field would have to be altered to reduce the wider parts to the lower design to be removed. You coin shows altered devices from a contact mark and also reduction of size from die abrasion. So the coin is altered two ways, but neither give it a premium. Also the die that struck your coin was also showing
Die Deterioration also on the coin you found. So three events happened on your coin, but still no premium. More of an educational coin that show what can and does happen before/after coins are struck.
