A rare and massive gold nugget, weighing around 20lbs (9kg), has been put up for sale 23 years after it was discovered and it’s expected to reach at least $1 million at an auction that takes place on Dec. 8.

The Alaska Centennial Nugget, estimated at the size of a baby’s head, was discovered by gold miner Barry Clay near the town of Ruby, Alaska, in 1998, 100 years after the 1896 Klondike Gold Rush.
