These are the prototypes:
They never made it to the market. I am sure they would have been a hit.
Flash forward a few years (decades) later, and the people putting together the Collector's Track panels at Star Wars Celebration came up with the idea of giving away coin/medallions to attendees, such as these:
These were a big hit so when it came time to come up with a new giveaway for attendees, they combined the relatively lower cost of "2D" die cast vs 3D action figure with the Star Tots idea. At each panel, a different Star Tot was given away. This is the first set from A New Hope at Celebration VI in 2012 in Orlando.
