It's the ultimate dream of everyone who loves to browse flea markets and antique stores: digging up some forgotten treasure that turns out to be worth a fortune.
For most people, that dream involves going on Antiques Roadshow, where experts travel around the country looking at different antiques and revealing which ones are worth WAY more than their owners expect.
While the show has been around longer in Britain, the American version turns 20 this year, so we've collected some of the most interesting and valuable antiques from the show's history.
We've added some great examples from the UK as well, but no matter where you live you should start looking through your attic to see if you have any of these great finds tucked away behind your old silverware.
1. Norman Rockwell's "The Little Model" - $500,000

2. Winston Churchill's Cigar - Around $1,000
Supposedly, Churchill smoked this cigar while planning the D-Day invasion. It may be worth more, another cigar chomped by the famous Prime Minister sold for nearly $2,500.
