George V 1917 London Mint Gold Sovereign

The George V 1917 London Mint Gold Sovereign is considered the rarest London-struck Sovereign of the 20th century. Its value is driven by its extreme rarity, as most of the original mintage was sent to the United States and subsequently melted down.

Estimated Value
Current market prices as of March 2026 for this specific London-minted coin (which has no mint mark) are significantly higher than standard bullion sovereigns:
Mid-Grade (VF to EF): Specimens in this range are typically valued at approximately £12,750.
High Grade (Extremely Fine – EF): The Royal Mint has listed high-grade examples for £30,000.
Uncirculated / Choice (AU58 to MS63): Premium specimens can range from £27,500 for an AU58 grade to as much as £42,500 for an MS63 grade.

Mintage
Official Mintage: The London branch of the Royal Mint struck 1,014,714 gold Sovereigns in 1917.
Rarity Factor: Although over a million were struck, they are “supremely rare” today because nearly the entire issue was held as gold reserves and later exported to the U.S. to pay for war supplies, where they were likely melted in the 1930s

How to Identify the London Mint
Mint Mark: Unlike branch mints (such as ‘P’ for Perth or ‘M’ for Melbourne), Sovereigns struck at the London Mint have no mint mark.
Location: Look at the ground line above the date on the reverse; if it is blank, it is a London-struck coin.
