1. Different JJL Dates
2. Different shades of grey
3. The foot stamps on the bottom.
All Iron Man 3 pops were bought from Facebook groups so I don't think they're fake. But I would love any insight if someone thinks otherwise. The JJL dates to me make sense since a first wave of them could have come out in January 2013 and then more produced for the May 2013 release. I also found eBay and Mercari listings with both JJL dates. I couldn't find anything about War Machine variants so if its a known fact, I was completely unaware.
