Hi I am writing from Italy my name is Totò Scimone,me.I am a Metaldetectorist and during an afternoon hiking with my Simplex I found someting concerning the New Croton dam, could you help me to understand what is this. Thanks totixit@yahoo

I am curious what you sound! Is it a commemorative coin? When the new Croton dam was completed in 1897 it was the tallest dam in the world! The dam creates the reservoir the supplies drinking water to New York City, it is also the centerpiece of a beautiful Park and trail system. Perhaps you can do an internet search of the new Croton Dam to find out more, or contact the Croton Historical Society. Good luck!

It's a water reservoir.
