Well, I dont normally even consider dimes, much less ones I can't spend, but I came across this today nestled perfectly atop some foliage. Couldn't hurt. At first glance it just looks like cracked die reverse maybe, but then I magnified to see some strange helical cone neatly placed in a spot that leaves me pretty dumbfounded as to what it is. Note all of the other detail on both sides of the coin that are pointing towards more than one error. But hey. what do I know about coins?
