How to Identify the Triple Unite

Begin with the obverse figure. A Triple Unite shows Charles I as a crowned, armored figure with curled hair holding a sword in one hand and an olive branch in the other, ringed by a Latin royal legend. This armed standing portrait, rather than a simple crowned bust, is the first strong clue that you are looking at a large Civil War gold piece and not an ordinary unite.

Read the reverse legend and date. The declaration RELIG PROT LEG ANG LIBER PAR, arranged around a central heraldic panel or scroll with a date such as 1644, is specific to Charles I's wartime issues. Look also for a mark of value indicating three pounds, which confirms the 60-shilling denomination and separates the Triple Unite from the smaller unite and half-unite that share related designs.

Assess size, weight, and fabric. The Triple Unite is exceptionally large and broad for a hammered coin, noticeably bigger than any unite, and struck on a thin gold flan with hand-cut lettering and slightly irregular borders. Weigh and measure any candidate against published specifications; a coin that is too small, too light, or too regular in its edges should be treated with suspicion.

Locate the mint mark and attribute the mint. Small symbols in the legend indicate the issuing mint and period, with Oxford and Shrewsbury being the relevant royalist mints. Cross-reference the mark, the exact wording and spacing of the legends, and the layout of the reverse against a standard reference for Charles I hammered gold to pin down the variety.

Be cautious with authentication. Because the Triple Unite is famous and extremely valuable, it is among the most copied English coins, and cast reproductions, tooled surfaces, and outright fantasies exist. Watch for casting seams, bubbles, unnaturally smooth fields, and lettering that lacks hand-cut variation, and given the sums involved have any candidate examined by a specialist or submitted to a reputable grading service before purchase.
