I found an international clad spill. It was located close to the river and it was swampy soil. The coins were very crusty. Once I determined they were clad, I used a brass bristle brush to clean them up enough to ID. Unfortunately with the exception of the Itilian Lira I still have not been able to identify the coins origins.
Each coin is the size of a quarter.
Any idea where in the world these coins originated?
