neat little key "coin" for GM vehicle vintage

Here is a neat little key "coin" from GM. On the front it says Saint Christopher Protect Us and an emblem of Saint Christopher on it. The keys aren't regular keys, but they fold out from the round keychain if you will and then fold neatly back in again with just the tips sticking out for access. Is gold in color as background on front, and the rest of the keychain is a silver color.
