Alien currency was not all that different to our own.

Usually when creating alien worlds and other universes layout artists and animation artists are encouraged to make objects appear very different to what we can see in our own lives everyday. However, when it came to finances, Filmation seemed to joke about and on a few occasions we saw that the alien methods of payment were not all that different from our own!

In He-Man's "Quest for He-man" Plundor, alien from another world desires to become rich. And thanks to Filmation we get to see his thoughts of wealth. Yet, those signs look a lot like dollar signs don't they?

In She-Ra's "The Inspector" Spyster is paid by Hordak after he tricks the rebels. Again, the sign on the bag is very similar to that of a dollar sign.
