On Monday night's episode of "Antiques Roadshow," a very special portrait painted by American artist and sculptor Frederic Remington was given a price tag even the owner couldn't believe.

"This piece, together with the letter, would be something that I would value at auction between $600,000 and $800,000," said appraiser Colleene Fesko on "Antiques Roadshow."

"Oh my goodness! I was hoping I would be wildly exuberant. I am," said Ty Dodge, the painting's owner.
