Will California Chrome become a triple crown champion?

For a horse about to run the race of a lifetime, California Chrome doesn't seem all that nervous. Completely in charge is more like it.

Father-son training team Art and Alan Sherman say that's just one trait that sets the 3-year-old chestnut apart.

"I'm really confident in this horse, period," Alan tells CBS News' Michelle Miller. "As long as he gets a little racing luck and he runs like he's been running, I think -- we're the horse to beat for sure."

At 77-years-old, Art is reliving victory from when he was an exercise rider on the Kentucky Derby champ Swaps in 1955.

"It makes everybody dream that they can come up with a horse like California Chrome," says Art. "That's why we're in this business. It took me 60 years."

It's been a heck of a ride for the colt's owners, too. Steve and Carolyn Coburn bred him for just $10,000 in 2011. He could now be worth tens of millions.

"We know that we were blessed and that it doesn't happen to many people the way it happened to us," says Carolyn. But the couple from Topaz Lake, Nevada, won't even entertain the thought of cashing in on their prize.

"We were offered $6 million for 51 percent, which is controlling interest," recounts Steve. "The answer was not only no, but hell no."

Since teaming up with jockey Victor Espinoza in December, Chrome has torn up the track, winning six straight races including the Derby and Preakness. If he wins Saturday, he'll become the first triple-crown winner in 36 years.

"I believe he runs not only because he loves what he does, and he does it very well, he's got the heart for it and he's got the mind for it, but I believe this horse is running because all these people are coming to watch him," says owner Steve.

The Coburn's believe California Chrome has become America's horse -- a rags to riches tale in the sport of kings.

"It's just amazing," says Steve, "it really, really is, that this one little horse has brought so many people together and put the hope in America again... The working class guy you can do it. Your dreams can come true."

Last month there was controversy over whether Chrome could wear a nasal strip that helps him breathe better. The New York Racing Association has approved it.

No doubt the crowds will be out, hoping to see history made.
