Last year I posted a picture of a variety of the Riviera 50c Inlay chip that I had not seen before. It had the denomination offset to the right. I see it was picked up in TCR in the last edition.

I had a chance to go through several additional chips and believe there are still more varieties. All appear to be the result of different artwork, not a printing variation or defect. Take a look at the four pics below and see what you think. There are two each of the regular (BURT) H&C mold and two with long cane mold. Notice that there are'high denom' and 'low denom' varieties on
the regular H&C mold.

If you have a chance, take a look at your collection and see if there are possibly one or two more that I haven't shown.
