Paramount's Transformers Metalpak- 2 different covers?

[silverlakephil]

I was at the Rosemead Walmart here in L.A. and I noticed the Transformers metalpak had two different covers. One has the Transformer with blue paint, and the other cover has a different Transformer. I think this is a manufacturing mistake since they used the back cover as the front for the non-blue Transformer. So you actually have the Transformer upside down! Not sure if this will be rare and valuable, but I'd thought I'd give you guys a heads up. Check post #156 & #160 in the main Paramount metalpak thread for comparisons, since I didn't have a cellphone to take pics.
