Hi Tom.. If your two SCROLL examples are also notched, I wonder if they're simply samples and were never usd in play.

The VC logo is interesting as well...

Could it also be that the property (gaming operation) wasn't fully Playboy at the time of manufacture and that both Playboy and Norwich were unsure as to what all should be on the inlay...?

Date of manufacture would be interesting at this time (both litho and embossed).
