No geo-theif in their right mind would leave a coin saying it was them (excluding fake accounts) that stole the coin, thus I must conclude A: its not stolen or B: they are bonafide crazy.
Which brings me to being 99.9% certain that someone associated with or the owners of The Bug Mugglers Hotel have taken the TBs without logging them. With the plan to place them in The Bug Mugglers Hotel cache as noted on the wooden nickle (the wooden nickles not being meant as a replacemnet). Other TBs said to be in the cache but arnt are not related (so too IceCreamMan's log).
I would recommend to The Trophy Hunters or whomever that they do not leave the TBs tracking number
but its reference number (TBXXXXX) on the wooden nickle.
