As Gene said, they mass produced them 'after the fact' (all part of the deal) for the home market. 7 denoms $5 - $100,000.
The movie used $500 to $100,000 only.
No way to tell them apart, but, I have a set that were used on-screen, guaranteed
I showed them on this bb the day after the premieres, several months before the mass production began.

Invitation cards to the premieres had a chip attached. A friend in the business got an invitation. He asked around for me and picked up a few chips people didnt want.
