Thanks for the good news. It is fun hunting, but nice to actually have a find.

Wow...cool find!

The clad strip is created by rolling three layers of metal together under very high pressure. To get proper bonding between the layers they need to be very smooth and very clean If there is an area that isn't clean the layers don' bond well and when a blank is punched from that area it is possible for that loosly bonded layer to separate from the inner core. Sometimes it will separate before the coin is stuck and sometimes it doesn't come off until after the coin is struck.

As for what might make it come off, well the edge squeezing when the blank is run through the upsetting mill, or if it is really loose the force of the blanking may do it. Then there is the dropping and tumbling that can occur anywhere along the way.

I recently inherited my grandfather's house, he always had an interest in collecting coins. A few years ago he gave his organized coin collection to his great-grandchildren. Needless to say, my kids have a better collection than I will ever have. My grandfather was a small convenience store owner for over 50 years. As we have begun remodeling this house, we found a large stash of rolled coins, in the cedar pantry. We assume these coins must have come from the change at his store. Over the next few months, we plan on searching through each roll with hopes of finding some treasure. Based on the looks of the rolls, there appears to be a lot of silver. This modern coin, definitely stood out amongst the others.
