I found this going though some change. Its the size of a quarter and both sides look the same. from the writing I'm assuming Japanese. Though if so I'm assuming its not a coin? Any help identifying it would be greatly appreciated.
You are correct in thinking that it isn't a coin. It is most likely a Japanese arcade token- potentially from a Pachinko or slot machine, with パルコ inscribed on it, translating to "Parco" the name of a Japanese department store chain.
