I don't know that there are a ton of posts about it, but on
eBay it is not uncommon to see the replica chips (what we identify as CDI98s) identified as "prop" chips. At some point someone intentionally or ignorantly described the green background label CDI98s they were selling as real "movie prop" chips. Those were never used in License to Kill. The red background label 10/50/100/500 and 6 black background label NCVs are the real movie prop chips.
This thread has some OK pictures of the denominated prop chips:
