What's loose in my Dark Souls LE?

[Gemini-Phoenix]

I bought the Dark Souls LE last week, but intend to keep it sealed. However, there's a suspicious sound of something loose inside and I am curious as to what it could be.

My initial suspicion is that maybe it's some kind of leaflet or art card, as these tend to rattle fron side to side in these kinds of editions, but the object feels somewhat heavier than that. M

My second thought was that perhaps it's a loose disc, but the sound and weight of the movement doesn't quite fit with a loose disc. Besides, X360 cases very rarely develop loose discs, and if they do then they don't usually move around as freely as this

I would describe the feel and sound more like a single dice or maybe a coin (like a 1p or 5p or Cent). If I rock the box from side to side, the loose object moves and seems to settle in the bottom-left corner - Except for the fact that the promotional pitures show nothing of that size which could be rattling around inside


Has anyone here actually opened their copy of Dark Souls who could perhaps shed some light on this?
