Did a bit of research into your coin which was last spotted in my cache on August 12 by sil. The next cacher to visit the cache was on August 15 by TCHNurse. I emailed TCHNurse today and she remembered the cache but did not see any TBs or GCs in there.
Hopefully someone visited the cache and retrieved your GC and will log it soon. I'll keep an eye out for any other trackables going missing from this spot.
