I can't say this surprises me much either. Stanislaus is full of a bunch of lazy asses (such as myself) who don't leave home to go to college and just want a degree so they can go pollute the state public school system. Not a school I would have relied on to conduct a survey for this trial.
At my school (University of Wisconsin) they actually have a survey center for this kind of stuff, and pay work-study students to staff it. It beat working at the cafeteria, and gave me a new appreciation for the hell that must be having a telemarketing job.
I wonder how much money George W. Bush gave Paris Hilton.
I think it's a magician's coin. But it is possible it is an uncommon strike. I used to have one that is similar but the back was a but depressed so I could put a dime in there for the old switcheroo. Try this page: http://www.faqfarm.
