I had this displayed for 2 years in a display case (out of direct sunlight). The reason for this is, the gold paint has an tendency to flake off and or tarnish on the shiny version. As far as the condition, I would say this is in the exact same condition as a new one with all original boxes and paperwork.
It looks to be the same as the day I took it out of the box. As you can see by the photos, it is like new.
