My first thought is copy based on the excellent condition and the lettering. But that is just a gut feeling. Hopefully someone will ID it for you. It may help to know where and how you obtained this.
Dan:
Can you post another pic of the obverse ('heads' side); with the same lighting--but this time set the lighting source 180 degrees from this first pic. Also can you place a penny into the scene for scale?
Thanks,
Don....
