Geodiamond
Santa Clara, California geocaching couple Geodiamond made this nice personal geocoin in August 2006. It is possibly the first geocoin with actual rhinestones in it, which adds a nice touch. I am not sure how many were made, but I do know there are at least 250 made and ten geocoins were minted in antique silver.
