Know What This Is?

While sifting through a container of board game pieces, I came upon this little metal charm. It's less than a half inch in diameter. I don't recognize it from any game. I don't recognize the symbol, either. Can anyone clue me in?

It very well could be something I found on the ground on one of my walks around the neighborhood. I may have dropped it in the container with the board game pieces so it wouldn't get lost.

Speaking of which ... I've taken many macro photos of classic board game pieces and will create a series of blog posts featuring them. It's a walk down memory lane for those of us who grew up playing many of these games, or played them with our kids.

As they say, "Watch this space."
