Identifying a rules set

[TauntaunScout]

I found a weird product as part of a WEG minis acquisition. It obviously came from some core rule set but I have had no luck figuring out what! I am very interested in all editions of the core rules. Anyways what I found was a bunch of little 1cm square chits that have top-down pictures of stormtroopers, AT-ST's and a bunch of characters. The characters are the same top-down graphics of Han, rebel pilot, and rebel trooper that were used in the old minis book for examples plus one that looks like a Luke graphic. Those are also printed with PC 1, PC 2, etc. There's also a couple named NPC's. Any idea what set these are from? They aren't the same stand-up ones as from the Mos Eisley Shootout, or the WEG Introductory Adventure Game.

Just a wild guess, they can be some form of token form the boxed set, usually boxed sets contain some grid maps and a few tokens, this sounds like something like this

Yes that's exactly what they appear to be. But which boxed set? All the ones I've found have distinctly different cardboard elements to them.
