What are the rarest and most valuable coins bearing the image of Queen Elizabeth II?
 
Her Majesty Queen Elizabeth II passed away at Balmoral Castle on September 8, 2022, at the age of 96. Her image has appeared on coins and currencies from at least 45 nations.

In 2019 the Perth Mint in Australia issued a $200 coin minted from two troy-ounces of pure 24 karat gold for the 200th Anniversary of Queen Victoria. This is one of the rarest coins ever issued showing the image of Queen Elizabeth II, Queen Victoria’s great-great-granddaughter. In 2015, Queen Elizabeth II surpassed Victoria as the longest reigning British monarch in history!
 
Only three hundred and fifty high-quality proof strike coins were struck in the rarely seen two-ounce gold format. The term proof refers to the method of manufacture and not the condition of a coin. Proof coins are made on specially prepared and highly polished coin dies and is struck multiple times under intense pressure to ensure the highest quality strike.
