Need Help Identifying US Coin

The coin at one time was normal, bu the reverse was altered to make a 'Love Token.' The reverse was sanded off and the initials were added. You can still see where there was at a time where there was a loop was solder on the top of the coin at 12:00 on the obverse. It was a piece of jewelry. Still a collectable, but not as a coin. They were made sometimes honor people, events such as weddings, birth years or other events. But that is what you have.
