That is a masonic symbol stamped into the coin. I have 3 similar to yours, on a 57, 69, and 81 cents, the 69 and 81 are also chrome plated. The square and compas have been their symbols for centuries, don't remember what the "G" stands for. Don't know alot about them, my understanding is the Free Masons would meet in secret areas, there would be hosts at the door verifying you were a member, the stamped coin was your ticket to get into the meeting. I also heard that since most of the members knew each other the coins were given out by members to people they wanted/ showed an interest in joining so they could gain access to the meeting. I am sure if I am wrong on this someone will correct/increase my knowledge so we can both learn.
