The Treasure Hunter's Roadshow may resemble a quaint local gathering - but it also promises to reveal some seriously valuable collectible items.
More than $1.2m worth of silver bars are set to appear at the next event in Cleveland, US, brought along by a local resident who found them buried on an Illinois farm.
Four gold coins purchased for more than $72,000 and a 1960s vintage guitar last bought for $100,000 will also appear, the event's PR director Matthew Enright told local newspaper the Cleveland Daily Banner.
The Treasure Hunter's Roadshow has visited more than 600 cities throughout the US and Canada since 1996, and travels more than 300,000 miles a year.
Its organisers reportedly purchase an incredible $15m worth of rare items for their collectors network, each year.
The 'treasure hunters' make offers based on what collectors are willing to pay, said Enright.
When someone decides to sell, they get paid on the spot and the treasure hunters send the item to the collectors at their expense.
"Collectors are very serious about their hobby," said Enright. "So serious that they will pay a lot of money for the items they are looking for.
"Nearly all coins, vintage jewellery, musical instruments and toys made prior to 1965 are highly sought after by collectors.
"Our treasure hunters are hoping to see items such as coins and paper currency issued prior to 1965.
"Toys, coins, dolls, trains, vintage jewellery, old and modern musical instruments, war memorabilia, gold and silver jewellery, advertising memorabilia, swords, knives, daggers and the unusual," he said.
"We are here to buy the items at fair and honest prices. Our expert associates are loaded with information, and it is all absolutely free."
The next roadshow stop will be Cleveland, US, for five days from August 25 to 29, reports the Cleveland Daily Banner. It will be held at the Wingate by Wyndham at Exit 25 on Interstate 75.
