This was one of the older chips that was in play at the Hacienda shortly before they closed. Although it's dated 1974, you could have picked one up for face in the 1990's. Still not common, as not too many 100 collectors even today. As I recall, I paid $150-200 for mine several years ago.
A historic chip, and one needed by every collector of Paul-son metal inlay chips!
The Stardust similar 100 sells for $400+, unless a pile of them was carted off after the casino closed. I don't know that any were in the vault; just speculating.
