Antiques Roadshow expert left 'entirely speechless' after guest hands them gross and disturbing item to be valued

There have been some crazy finds on Antiques Roadshow, but this may have topped the list for most bizarre.

Since it first aired over in the UK in 1979, experts have revealed that some of the dusty antiques lying around in peoples attics could be worth the big bucks - including the time an original Anthony van Dyck painting was discovered in 2013.

The artwork, which was only purchased in England for £400 by Father Jamie MacLeod for its frame, turned out to be worth around $525,000.

The hit show hit screens across the Atlantic Ocean in the US in 1997, and American punters soon discovered their junk could be worth millions.

In 2004, a pocket watch - created a century before in 1904 by the luxury Swiss watch manufacturer Patek Philippe - fetched a staggering $1.5 million dollars for its owner.

Fast forward seven years, another find landed $1 million - that was a set of ceremonial cups forged out of the horn of a rhinoceros.

But that doesn't mean we're all sat on a small fortune - something which one UK resident discovered when he brought in an odd and somewhat stiff decoration.

The guy came on with two items he wanted valuing, the first was a cigarette holder for ladies which consisted of a 'canary yellow enamel case' which he explained was given to him as a young boy.

Speaking to host Penny Britain, he said: "It was given to me by a very old lady when I was about seven and I remember to this day she was Austrian and she gave it to me in a cardboard box full of trinkets.”

She confirmed it was Austrian and dated back as far as 1900, valuing it at £100 - which is roughly $131.

The next was a hard-on for Britain to value.

Digging it out of his pocket he hands it to her before asking: “Could you tell me, is that worth £100 and made in Austria?”

As she begins to laugh hysterically, he whispers into Britain's ear: “It’s a mummified dog’s willy.”

To which hilariously she responds: “A mummified dog’s willy. And I’m holding it!”

The crowd all burst into laughter before Britain added: “I’m rendered entirely speechless.”

I mean... I think we all would be!

So why does he have a mummified dog's willy?

“It’s been passed down the family literally for years," he explained.

"This bit’s a bit gnawed because the puppy got hold of it and my father, when it came to him, wanted to throw it away and I said, ‘You can’t because it’s so extraordinary'.”

He then asked whether it was worth £100, to which Britain laughed: "I don’t think so.”

Maybe hop on a plane and take it to Pawn Stars... I'm sure they'd give you a price!
