The Royal Mint UK has produced a 5kg coin that is reportedly worth a staggering $500,000.

The coin features the “Una and The Lion” design, conceived in 1839 by William Wyon. He was the former official chief engraver at the Royal Mint.

The coin design is made from fine gold and has been remastered from an original die that was first used almost two centuries ago.

The ceremonial gold coin has been tested by the Goldsmiths’ Company in the City of London to ensure it is of the highest quality.

A coin weighing two kilos and worth nearly $250,000 has also been made featuring the same design.
