the Autobot one. if you can read the copyright date beneath the hasbro logo (on the back) it may clue you in. my guess is that it may be the 2007 one. i don't see blades, or hooks and the package gives the impression of it being leader class. TFU.info has a gallery of pics beneath each Optimus Prime entry to show all the other versions and variations. you could compare until you get it right.
I believe it's a Premium release with battle damage. Not sure exactly where this was released solo, but in the US this figure was released as part of a 3-pack with battle damaged Arcee and plain Starscream.
Sold a couple of these back in '07. This Battle Damaged Optimus Prime was released as part of a 3-pack as well as individually. The 3-pack was a Sam's Club Exclusive while this one was somehow rumored to be a Best Buy Exclusive. Nevertheless, I think I "conveniently" put him under TRU label when I was selling him back then.
Yea, I don't think the solo ever saw release stateside. I posted the same topic about a year ago and only got the 3-pack and Robo answers. It did start showing up online at the tail end of the 07 movie line.
The people above are correct. This is Premium Battle-damaged Optimus Prime released only in Asian markets. It is the same as the the one in the Sam's Club 3-packs in the U.S. and it cost about $30 USD. Robot Kingdom has it now: robotkingdom.com -- Online Toys Company In other words, it has a higher retail price than an American Transformers Voyager toy.
