I am the last person to see this Geocoin. I dropped it in Villa Park Geocoins along with a Geocoin and then the cache was destroyed. The cache owner (CO) reported evidence suggesting an animal attacked the cache. He found the Geocoin's plastic sleeve on the ground. I expressed my disappointment so the CO spent 1 hour with a Metal Detector searching GZ! Unfortunately they didnt find anything. We did our best, hopefully the TB still turns up somewhere.
My apologies, wish I had placed it in a different cache but of course I couldn't have known.
