I collect varieties. I don't believe every H&C chip will be found with both variations. I care about the differences if they are chips that fit my collecting interests, Pete.

I need to distinguish between them and want to have different catalog numbers, even if both types are equally rare (or scarce). What TCR has been doing is the best approach, in my opinion. Doesn't matter if one is more common than the other, but that is useful information if it is the case.
