Found today in my back yard. My house was originally built in 1900 but the town dates to aprox 1840. I don't know if the property was lived on before this house was built. This item shows as a +14 VDI, same as a nickel. The emblem on it looks like a large horse shoe with a small horse shoe inside of it, then a large letter i through the middle of both. They could be letter C's. The top of the flattened round part tapers thin at the top, almost as if you are suppose to hold it with your fingers and twist it back and forth into something. Both sides look the same.
