A halfway decent point-n-shoot digital camera will do fine. I am not a fan of scanning coins. John1

That is called split plating. During the strike, the plating was split showing the zinc underneath. It get worse with time and the oxygen getting to the zinc.

What causes split plating? John1

The movement of the metal during the strike exceeds the ability of the plating to "stretch" that far (especially at sharp device and field junctions near the periphery where he metal movement is greatest.) so the plating splits and a gap opens up.

The business strike coins are struck just once (normally). So if you see three marks on the coin, then it is machine damage from the dies being loose. No premium for these. Just coin damage. I save the extreme ones into a tube in case I need images for a future discussion. Then they go back into the tube. The common ones, I put back into circulation.

So then why does it not happen on all zincolns all years and MM's? Thanks all. John1

Is there slight die movement maybe when the strike occurs?
