I would think that with judicious use of "HOUSE" mold, 100 defined codes would be sufficient, even for foreign casinos.

Given that a few issues have more than one kind of BJ mold, I do think the BJ defined mold codes should be broken out with DIECAR, 8SUITS, etc.

None of these ideas work though unless the administrators have the list of acceptable codes and something verifies codes loaded for new chips.
