Got my answer after super duper close micro inspection on a close up macro shot, it has some grime build up between the limbs, so most likely someone has just home heat sealed it, told the guy who sent it to me & now he won't charge me for it, so there are still some very genuine collectors out there & its a refreshing change to deal with them.
It will be put in the fake baggies box in readiness for that index in the distant future.
Thanks for your thoughts guys
