Last winter I was fortunate to go to NY and see in hand Chief Farmer’s Brother’s small George Washington 1792 peace medal. It was an exciting visit and I was allowed to study the medal in hand and have the medal XRF tested.
The results showed that the medal was plated with coin silver and the plates were +60% silver that was mixed with a -30% copper. You can see the wear on the medal where the plating is worn and the plating area shows a copper color discoloration around the medal
The medal is in excellent condition and the only area showing the plating is around the outside circumference of the medal edge.
