Font sizes have varied widely over time, particularly with some colours. There are also different font types, spellings, etc.
The newest chips all have small fonts, though not all uniform sizes, particularly with the newest colors. Some of those new colors (avocado, petunia, etc.) were initially released on
RHC molds, but have since been replaced by
THC.
Individual colors have also varied over time, whether by formula or just (I suspect) variation between batches. I have two Hawaii Flower chips of different vintages that look more different from each other than the Hawaii Flower and Dolphin Blue from the same set.
