Don't have a screenshot but I found a Wizzard hat with the following stats:
Crit hit damage or crit hit chance (can't remember).
Unfortunately the stats were not very high but as I understood it this was a rather "perfect" drop for Wizzards so its sold for around 15 million.
Found this in act I and did around 10 other runs after that and found nothing really worth selling. Even with 200% magic find gear. Guess I'm just unlucky. Damn RNG!
