Those look an awful lot like standard dice chips and other cheap plastic stock lots readily available online (and it's entirely possible that the prop master just bought them online like any other consumer would and used them as props).

By no means am I accusing you of doing anything unscrupulous or unseemly, nor have I even seen the movie, but since the chips in your photos look similar to many home line chips - and the chips in the movie may very well be the same things that we could buy online from various retailers - how is a buyer to have confidence that the specific chips being sold were indeed used in the movie? How would they be able to differentiate what you're selling vs. any other chip bought online from a chip retailer? Do they come sealed with a signed certificate of authenticity from a known authenticator or something to that effect?
