Thank you. It was dug in a sandy mix type soil along a pathway. Soil in this part of South Jersey is very sandy.. but there was some orange gravel mixed. The coin was very crusty when dug It. I have developed different methods for cleaning up certain coins. This one was olive oil soak with light finger polish with the olive oil. It takes time but works well. I use electrolysis for deep pited corrosion. I never "polish" silvers.
