A few weeks back, Shelby American showed off its 50th Anniversary Mustangs at the Detroit Auto Show. Prior to announcing the Mustangs, Shelby announced a limited run of 50th Anniversary Cobras, which quickly sold out.

The price of admission for a 50th Anniversary Cobra, sans options, began at $69,995 for a fiberglass-bodied roller designed to accommodate a 289 cubic-inch Ford V-8. For Shelby fans on a budget, it seemed like owning an anniversary-edition Cobra would require a substantial lottery jackpot.

Not so, says Autoweek, who tells us that the last 50th Anniversary Edition Cobra will be raffled off at next January’s (2013) Barrett-Jackson auction in Scottsdale, Arizona. Rather than crossing the block in a bidding auction, the winner will be picked by raffle entry.

Tickets, details here, are $25 each or five for $100. All proceeds go to benefit the Carroll Shelby Foundation, which helps provide financial support to the families of children battling life-threatening illnesses.

We can't find details on the exact raffle car, but it looks like a fiberglass-bodied Cobra equipped with a 289 cubic-inch V-8. That means it's packing some 475 horsepower, which is more than enough to be entertaining, and we'd gladly make room for it in our own garage.

The Cobra will be on display at events throughout 2012, including the Boca Raton Concours d’Elegance, the Dana Point Concours d’Elegance and Barrett-Jackson’s auction in Orange County, California.
