Abehunter

Does anyone know what these are,I can't post a picture, they are like a real small ( bite mark)(sprocket)and just to or 3 in row,I've seen the same marks on different coins,

Can't be certain without pics, but it sounds like contact marks from being hit by the edge of a reeded coin

Striking coins only builds up a very small amount of frictional heat. Nothing anywhere close to the melting points of metal. The marks are caused by simple physics (F = ma) and metallurgy (metal deformation)

I'm guessing that doesn't help the grade of a coin or is that overlooked?
