"The metal inlay in your chip (and mine) says "Silver Anniversary""
It is not a metal inlay.
It is a paper sticker. They are easily removed with an exacto knife and put on any Bud Jones chip.
See Texas chip below. My sister found this while playing poker. She was so excited she found something I would want, I did not have the heart to tell her what it was. A bored (Dave Whalen) poker player did this between hands.
