What is a "wheel mark"?

UncleDano

I was looking at a few nickels on Great Collections auction site, and came across one with the designation of: "wheel mark UNC details".
I looked this coin over both sides but don't see anything that strikes me as a wheel mark, just the usual bag marks.

Anyone know what a wheel mark is and what it looks like?

A "wheel mark" is counting machine damage. The rubber roller that spits out the coins into a bag is what causes the damage. When the coin gets stuck and does not immediately get ejected from the counting machine the damage occurs. It would probably show up if you rotated the coin in hand.

I believe it is the same as a Counting Machine Mark and is considered damage.

The back kind of looks like it has some unnatural dark areas. Like something rubber rolled over it???
