'Antiques Roadshow:' Letter from Galileo is worth thousands

A letter penned by Galileo Galilei, the father of modern science himself, was valued at a surprisingly high price on Monday night's episode of "Antiques Roadshow."

"It's perfectly clear, the condition is excellent, it's been well looked after. I would give this an auction estimate of $60,000 to $80,000,"said appraiser Francis J. Wahlgren on "Antiques Roadshow."

"Oh, my God, wow," said the letter's owner.

Yes, this lucky woman inherited the rare letter from her grandmother, who got it as a gift from her great-grandmother in the late 1940s.

And even more astounding than the whopping $60,000 to $80,000 appraisal? The letter was originally purchased for just $170 at an auction.

Apparently, Galileo's John Hancock is extremely rare and is one of the most sought after autographs ever.

And the letter happens to be in immaculate condition too, which convinced the "Roadshow" appraiser to recommend it be insured for at least $100,000.

Fans on Twitter couldn't believe how much the letter ended up being worth, calling it impressive and amazing.
