Here's one from 1993 advertising the second series of figures. Note the heavy emphasis here on TOS characters in the top row. Curiously enough, Scotty and McCoy were two of the most under-purchased figures on store shelves, by a huge margin. Were those overproduced?
Playmates tended to underproduce the weird aliens, so Dathon and Vorgon were certainly produced in smaller numbers, but Lore was not. K'Ehleyr seemed to be harder to find, which often happened with female figures as a matter of course.
