How to Identify the Charles II Five Guineas

Begin with the portrait. The obverse shows Charles II facing right with a laureate head and long, curling hair, draped at the shoulder, encircled by a Latin legend naming him king. This mature, curled-hair profile on a large gold flan is the first thing to confirm, and it separates the coin from the very different hammered gold of earlier Stuart reigns.

Read the reverse carefully. Look for four crowned shields bearing the arms of England, Scotland, Ireland, and France, set in a cross (cruciform) pattern with scepters between the shields and a linked motif at the center. This cruciform shield layout is characteristic of Charles II's milled coinage; a single shield or a different arrangement points to another type or reign.

Assess size, metal, and edge. The Five Guineas is a large, heavy gold coin, the biggest gold denomination of the reign, so weigh and measure the piece and compare it against published specifications to separate it from the smaller guinea and two-guinea pieces. As a milled coin it should have a regular round flan and, typically, an inscribed edge rather than a plain or merely grained one; the edge lettering is an important authentication feature.

Check for provenance marks. Some strikings carry an elephant or an elephant-and-castle below the bust, marking gold from the Royal African Company. Note whether such a mark is present, as it affects attribution and value, and confirm the date in the legend, since dates and varieties vary across the reign and matter greatly to identification.

Authenticate with care. Because the type is famous and valuable, cast copies, electrotypes, and modern replicas are common. Watch for casting seams, bubbles, soft or mushy detail, incorrect weight or diameter, a wrong or missing edge inscription, and lettering that lacks the crispness of machine-struck work. For any coin of meaningful value, seek an opinion from a specialist in English milled gold or a reputable grading service before purchase.
