So recently, I got a boxed 1984 pre rub symbol G1 Mirage which is near mint. I've never seen a Mirage with joints this tight. Anyways, I already have a loose G1 Mirage from a few years ago and I put them side by side and noticed my older loose Mirage has a deeper blue whereas the recent boxed pre rub Mirage has a bit of an almost turquoise-ish tint to it. Is this due to sun damage over the years or did the earlier '84 Mirage figures have a more turquoise like color to the blue? Any help would be appreciated!
