Strange Silver Pack

I was gifted this pack as part of another lot of cards. I'm not sure what to make of it. It feels as if it contains more than one card, so that rules out the manufactured patch card. Box Toppers are usually in a specially marked pack. 
I am at a loss.
Only one thing to do- rip.

Ahh so the answer is simple. Purple border Topps Chrome from 2013.
