1 Unite - Charles I Pattern

The Unite was England's primary gold denomination under the early Stuarts, valued at twenty shillings. Pattern issues from Charles I's reign are notoriously difficult to attribute with precision — many were produced by Nicholas Briot, the French-trained engraver who joined the Royal Mint in 1633 and immediately began challenging the entrenched hammer-men with his screw press techniques. A 1630 date places this piece in the transitional window before Briot's machinery was formally adopted, when experimental strikings were circulating privately among court and treasury officials rather than the general population.

North 2656 is a rare reference point, with confirmed survivors numbering in the single digits across major collections.
