About these coins
James I, who united the crowns of England and Scotland, struck an extensive coinage organised into three coinages across the reign. His gold includes the unite (twenty shillings, named for the union of the kingdoms), the laurel, the spur-ryal and the great rose-ryal of thirty shillings; his silver runs from the crown and half-crown through shilling, sixpence and the smaller coins. New mottoes and the royal arms of the union appear throughout.
Shillings and sixpences are the most widely collected and attributed by coinage and mint mark; the gold unites and laurels are scarce and handsome, and the large rose-ryal is a prized rarity. Coinage period, denomination, mint mark, grade and provenance set the value.

What drives the value
Type & rarity
Within a single reign, common types in collectable grade sit far below the scarce and rare types. Identifying the exact type is the first step in any valuation.
Mint & moneyer
Coins of rare mints, or with sought-after moneyer or privy-mark signatures, carry a clear premium over the common major-mint issues.
Grade & surfaces
A full, sharp strike with a clear portrait or design and legible legends commands the most. Weak striking, chips, cracks and corrosion all reduce value.
Provenance
A pedigree to a named cabinet or a recorded hoard adds both value and confidence in authenticity, especially for scarcer and higher-grade pieces.
Frequently asked questions
How much is a James I coin worth?
Shillings and sixpences are widely collected and accessible, while the gold unites and laurels are scarce and the large rose-ryal is a prized rarity. Coinage, denomination, mint mark and grade set the figure — use the valuation tool for an estimate based on realised prices for comparable coins.
Why is the gold coin called a 'unite'?
The twenty-shilling gold unite was named to celebrate James I's union of the crowns of England and Scotland, a theme reflected in its legends and the combined royal arms.
How is James I's coinage organised?
Into three coinages across the reign, distinguished by changing titles, designs and mint marks — which, with the dated sixpences, allow the coins to be placed in time.
