I'm not sure if this is the place to ask....I have a Ken Griffey Jr Coin that has a serial number stamped into it...I'm not sure of who produced it.....can anyone give me some heads up as to where I might look to get some idea of what I have?
The only coin I know about is the Pinnacle mint set around 1998. There was a bronze, nickel, silver and gold coin..there was also a card with a hole in it where you could place the coin into it. Not sure if the gold or silver cards were serial? I only have the bronze and nickel coins. It could be the artist proof coins is it serial to 500? Best regards, David
