What causes this? (Indian Head Cent)

I've seen this on more than one occasion. Any idea the cause of it the defective looking deticles? Really apparent on the reverse.

I don't think so, unless it was mounted in jewelry and then never used. The coin has full luster.

There exist coin bezels with crystals (glass) on both sides that protect the surfaces of the coin, but still cause damage to the edges. Here is a page with some modern examples, although these are solderless.

The first cent encasements were for the Buffalo Fair (1901) where McKinley was shot. He could have used one that said "keep me for good luck".
That is why you don't see this sort of damage on earlier coins. They used new coins for the year of the event - there are lots of 1904's from the St Loius fair, for instance.
The coins are damaged when encased and should be kept in their encasement.

It really not silver colored, some strange phenemonenon with the lights and camera.
