20 Seniti - Taufa'ahau Tupou IV FAO

Historical Context: This 20 Seniti coin, issued by Tonga from 1981 to 1996, features King Taufa'ahau Tupou IV (reigned 1965-2006). His era marked significant post-independence nation-building for Tonga, following its full autonomy in 1970. The coin's "FAO" designation signifies Tonga's participation in the Food and Agriculture Organization of the United Nations, highlighting national and international efforts toward agricultural development and food security, crucial for this island nation.

Artistry: The specific engraver for this circulating issue is not widely documented, typical for modern national coinages. Stylistically, it adheres to a modern, realistic aesthetic. The obverse prominently displays a dignified effigy of King Taufa'ahau Tupou IV, usually facing right, encircled by royal titles. The reverse, reflecting its FAO theme, typically features a design symbolizing agricultural prosperity or a specific food source vital to the Tongan economy, such as local produce or fishing, alongside the denomination and date.

Technical/Grading: Struck in copper-nickel, this coin is substantial at 11.3 grams and 28.5 millimeters, designed for robust circulation. Key high-points for grading include the King's hair, ear, and cheekbone on the portrait. On the reverse, raised elements of the agricultural motif or numerical denomination are critical areas for wear assessment. Copper-nickel generally allows for a crisp strike, though circulating examples may show minor softness in fields or finer details due to striking variations or early wear.
