Unfortunately, the only real way of knowing for sure is by looking on the inside ring of the master CD itself. I've read plenty on checking on a bunch of different parameters to look for like serial number, stickers, box shaking (cardboard or plastic) and the list goes on. E-mail me and I'll point you in the right direction to finding a rare version that you need. (It's more expensive, but not as expensive as having 3 extra ones laying around!)
