I don't recall seeing this situation before. Riverside in Reno has black NCV's marked with Jessie Beck's name on two different chip molds. It's listed properly in TCR, but I'd never noticed it. They have different issue dates in TCR, so apparently the H&C mold is a reorder in '73 (2 years later). Interestingly, the SMCRWN chip stamp is about 10% larger than the later one so it wasn't just a matter of sending the tooling from T.R. King to Paul-son for the reorder. They made a new die.
BTW, I got the H&C in Doug's recent Reno auction at a price right in line with TCR's "I" value.
Does anyone have an example of another chip that was issued as a hot-stamp on two different molds? I can't think of one.
