For the Red Dragon collection it is noted that the 1 mil chip was made later, that's not true. They had them on set. They only made 5 - 10 from my recollection. They were made for the key players. director, DP, etc. The art department had a few more, which is probably where the ones seen around ebay and the like are coming from.

I worked on the set, but didn't collect chips at the time, or I would have had thousands of them.

Thought you'd like to know. They also had rubber chips made for the explosions. I haven't seen any of those since the days of filming.
