1837 Executive Experiment Altered Token?

There are a lot of people that alter coins for sentimental reason or wanting to remember someone or a special date in time. This is one way they can always cherish say a loved one. My Mother had the reverse of a beautiful silver eagle engraved with the birth date of my children and my sister's children. This is a way she chose to remember then. I collect coins so I think she messed up the coin but I guess to each his own.
