This listing is for a Vintage 1963 Charles Thomae St Saint Christopher Sterling Silver Charm With Key Chain.  The charm is engraved "Chip" and dated; it is also marked "Sterling" along with Thomae's maker mark.  We are not sure what the keychain's metal is; it does not have any marks and has not been tested.  It is in good vintage condition with age/use related wear and tarnishing.  Please look closely at all photos for condition.  If you have any questions, please message me.  Thanks for looking at my listing.
