Old miniatures
 

So recently I found my old CW miniatures, still sealed in the packs. While sorting them for eBay sales (see the Trading Post thread for a link) I noticed one was different.

One is labeled Steve Jackson Games, not Grenadier. I knew SJG had made the minis before Grenadier. Are SJG's versions more scarce than the Grenadier ones? Or is there much value difference?

Physically, the bubble is smaller, and there are only 3 minis in it as opposed to 4 like the Grenadier packs have. At least, this applies to the pick-up trucks pack-that is the one I have.
