I recently picked up this (I will call it a card). If anyone has any info as to how it was obtained I would sure like to know. The card, this one weighs just under 1 1/2 ounce of silver. As it says right on it. I have tested it and it is actually sterling silver. Blank on the back side. It is just a tad smaller than a actual slot or room key card.

Any info please......
