I don't think I've seen a thread like this, so here goes. I've only found a handful of IPs from CRH'ing. Here's my best looking one! The others are all nasty.
Came across this thread while searching for another one, cool idea. I've only found 3 CRHing, all nickels.. Sorry for incomplete images, that's all I have saved to this phone. 1964, 1983S, and 2008S
Thanks for reviving the thread! Here's one I got from the LA metro subway ticket machine, the only place I know of that gives change in dollar coins only!
