It's the real thing, Tyrus. They were used as business cards by Stardust management & executives. A few have appeared in Howdy Herz' & other auctions. The ones in very good condition such as yours, usually go for about 150.00. Most of them however, are in poor condition and go for much less. The $100 paper cards go for about 50.00 each & are probably what Rene saw. The $1000's were made in both paper & metal. They are not chips and had no value on the tables or in the cage, but they are an important collectible of the bygone days of the Stardust.
