Hey guys! So I got a handful of foreign coins from a guy who'd just used the coinstar machine. Most of them were Canadian with one Mexican one in there, and then there was this one. Being an amateur, casual coin collector, I don't know where this is from. The characters look asian to me but that's as far as I can guess. Anyone know what this is? Thanks in advance! Sorry if the picture quality is bad, I used the magnifying photo taking app on my phone.
