Anyone interested in bidding on these, an FYI these were not sent to Miramax for use in the film, but held back at the factory that produced them. From Jim:
"These Rounders chips were made for Miramax Films but were kept at the factory as samples. These were part of the factory, run but were not sent to Miramax. Therefore they were not used in the filming of the movie. Only Miramax Films can claim actual movie use"
