The frames and the wooden coin are both made with local (PA) hardwoods: Black Cherry and Sugar Maple at a local sheltered workshop in Ridgeway PA, about 40 miles from the GWIX venue.The plaque is two sided: you can flip it over to see the other side of the coins without taking them out. There were two versions of the keystone coin. The one in the plaque is unique to the plaque only and there were only 215 made. We only had 215 of the wooden ones made, too. (The volunteer coin is the same design but has a different finish.) The round metal coin is the official coin that most people got. All three coins are trackable. And believe it or not there are still a few available for sale! If you are interested contact me at my geocaching profile. --kcepenn
