You don't see this kind of higher-end product on the shelves of the big-box stores so I look out for this sort of thing when I'm at a card show. One of the dealers had loose packs of 2012 Panini Prizm. Pricey at $6 for a 6-card pack so I only bought one. The pack had 4 base cards and an auto. The 20-pack hobby boxes promises 2 autos per box so the insertion rate isn't too bad.
Here's what I got.
2013 Panini Prizm #69 Jose Reyes
2013 Panini Prizm #85 Kyle Lohse
2013 Panini Prizm #102 Alex Rios
2013 Panini Prizm #121 Frank Thomas
2013 Panini Prizm #153 Wei-Yin Chen
