I was able to work with the sell and get a refund on mine. Thanks for the tip though!!!
As far as the variant you mention. Yes, that is suspicious. I’ve seen many sealed copies of all variants, and the one you mention should be the older security seal. Even now on eBay all of those have the older seal except one copy.....that variant has a manufacture date on the back of 2003. From everything I have found and personal experience, everything with a manufacturer date of 2001-2003 has the older security seal. This includes black label, promo NFR, system pack-in NFR, and foil.
The platinum hits variant is always the newer security seal and was manufactured in 2004. Halo 2 has the same 2004 manufactured date and also always has the newer seal.
So for all the Combat Evolved copies (and maybe all Xbox games?):
2001-2003 - older security seal
2004-Present - newer seal.
Any other observations are welcome!!!
