Dennis - I saw that at the trade session, here is what you have:

It is from the MGM Grand Casino - Las Vegas
It is a NCV token (no cash value)
The design side is the Casino - the logo side is the MGM Lion
It was minted in Canada and it is 1 Oz of .999 Fine Silver
The mint was Jacques Cartier Mint
And it was issued in 1973
