Are you sitting down? You better be.

Recently, a museum in Northampton sold a statue of Sekhemka for £16m. A huge amount.

Sekhemka was an ancient Egyptian scribe and the statue dates to around 2494–2345 BC, making it slightly older than Stonehenge.

If we assume for a moment that Tutankhamun’s death mask is at least 1000 times more important then you can expect it to command an auction price of a mind-boggling £16 Billion.

This would make it the most expensive item to ever be auctioned.

The most expensive work of art ever to be sold at auction was a Leonardo da Vinci painting at an eye-watering £341Million.

This doesn’t even come close to the potential price of Tut’s famous death mask.

Of course, the likelihood of Tut’s death mask ever being sold at the auction is effectively zero.

It’s priceless.
