Though the U.S. has plenty of highly sought-after coins, it can be a good idea for coin investors to diversify their collections by adding international coins to their portfolios. Here’s a list of some of the most valuable foreign coins ever created.
The 1343 Edward III Florin

This is one of the most valuable foreign coins. It was minted in medieval England and was originally worth six shillings. Experts believe that only three of these coins are left in the world. Each one is valued at about $6.8 million. Considering that a shilling is worth about 24 cents, its value has certainly outpaced inflation.
2007 C$1m Coin
Created by the Royal Canadian Mint, this 99.99% gold coin is an impressive 100kg. With a value of $4.1 million, it’s worth more than its weight in gold. It was stolen from Germany’s Bode Museum in 2017. The coin hasn’t been recovered, and it’s assumed that the thieves melted it down and sold it off as smaller pieces of gold.
723 Umayyad Gold Dinar
Created centuries ago in the year 723, the Umayyad Gold Dinar was sold at an auction in 2011 for £3.7 million ($6 million at the time). It is believed to have originated in the Hejaz region of Saudi Arabia. It is made of solid gold and has an inscription that translates to “Mine of the commander of the faithful in the Hejaz.”
Silver Tetradrachms of Naxos
Tetradrachms hail from ancient Greece and were used for centuries. These silver coins were minted across the Greek empire, and many cities had their own variations. A tetradrachm from Naxos sold for $613,999 at an auction in 2016. This coin is believed to be from about 460 B.C. and depicts a bearded Dionysus along with his companion Silenus drinking wine.
