A gold half-florin of Edward III is to star in a sale of numismatics at Spink London on September 22-23.

It's expected to make £30,000-40,000 ($46,137-61,516).

Edward III claimed the throne of France as well as England

The lot dates to between January and July of 1344 and displays exceptional gothic art. It draws its inspiration from French coinage and indicates Edward's designs on the French throne.

These designs would lead to the Hundred Years War, which fundamentally altered the makeup of Europe.

Spink explains the lot is "an excessively rare coin of national importance.

"Many will recollect that Spink handled the last specimen to be unearthed in March 2013, which sold for £90,000 (incl. buyer's premium).

"These two examples of this excessively rare denomination comprise 100% of the known specimens which are available to the collectables market.

"There are just three others known to exist, two in the British Museum and one in the Hunterian in Glasgow."

Other lots include a Vitellius AV aureus of Rome that is expected to sell for £14,000-16,000 ($21,539-24,616).
