RARE Employee Gift Token from JACKPOT Enterprises

When Jackpot was listed on the stock exchange, the CEO had these tokens made and select employees received them to commemorate the event.

I emailed the seller. He personally received this token. It weighs exactly one ounce.
He believes it to be .999 silver because he personally knew the CEO and would not expect him to have anything but SILVER used to create a commemorative. It has no markings of the mint, nor of the metal content.

I feel it is worth the gamble, since it is from the 1980's.

Anyone have any thoughts?
