1343 Edward III Florin
Known as the “double leopard,” this coin is easily one of the rarest in existence. The Edward III Florin coin’s origins have been traced back to 1343, making it one of the oldest coins to ever be found at auction. Only three of these coins have been confirmed to exist in today’s world, which gives them an even more valuable rarity. One of these coins was found in almost perfect condition by a person using a metal detecor in 2006. That one find completely changed that person’s life because the coin sold at auction for $6.8 million!
