Following on form a previous post on the new licensing and Piracy site I wanted to share this new site on a similar topic.
'The new Counterfeit Gallery navigation includes the typical three types of counterfeit, high-grade or high quality, mid-grade quality and low-grade or low quality counterfeits.
Also included with this release of the counterfeit gallery is the ability to submit your own image. Here's some more detail about the categories of counterfeit you'll see in the gallery'
The site requires Silverlight, but you can see in detail how to tell if your physical software disks and boxes is genuine or not and the ways in which the counterfeiters go about trying to make there stuff like like the real thing.
Thanks to Alex for the tip
