Our workaround for the MIA/stolen geocoins is to now only send out a proxy. We photocopy the real coin - front and back - glue the 2 sides to cardstock and then laminate it with heavy grade laminate. You can cut it into whatever size you want then. That way the real coin stays safe with us forever. If/when the proxy disappears - we will just make another one and get it back out in circulation. We have lost too many TB's to put out the real thing anymore. You could also do this with the TB tags - make a proxy tag.
