Thanks, Bron!
I'd cash it for a small percentage if it was someone I trusted also.
There's something called the "Latino Lottery Scam" that I've heard about in Houston. A couple from Mexico will approach a stranger in a parking lot and explain that they won a large sum of money in the lottery (obviously not the jackpot, but usually a 5-number winner or a scratch-off) but they can't cash it because they are illegal. They present a counterfeit ticket to the person and offer to sell it to them for a fraction of the winnings. The naive victim then pays several hundred dollars for what they think is a ticket worth several thousand dollars, but instead worth nothing. The couple goes on their merry way with loads of cash and the victim goes to Austin to find out they didn't win squat.
