Depicts Saint Thomas Aquinas, wearing the habit of the Dominican Order to which he belonged. He holds a tome of his most significant work, the "Summa Theologica," in his left hand and a feather quill in his right. A shining sun on his chest symbolizes his great wisdom. He is most widely known by the title "Angelic Doctor," celebrating his exceptional purity of soul and body. In the background, on the left, are a lily, symbolizing chastity, and the Church of Saint Thomas in Roccasecca, the first religious building in the world dedicated to Saint Thomas Aquinas, who was proclaimed a saint on 18 July 1323 by Pope John XXII.

The top of the coin features the inscription 'CITTÀ DEL VATICANO' in a semi-circle from left to right. The bottom part bears the inscription 'Angelic Doctor Thomas Aquinas'. The date of his death is on the left, and the issuing date is on the right, with the engraver's privy mark on the left and the mint mark (R) on the right. The outer ring displays the 12 stars of the European flag.

The Summa Theologiae, also known as the Summa, is Thomas Aquinas's most renowned work, intended as a comprehensive guide for theology students. Covering topics like God, Creation, Man's purpose, Christ, and the Sacraments, it synthesizes Aquinas's mature thought. Despite being unfinished, the Summa is a classic of Western literature and theology, citing diverse sources including Christian, Muslim, Hebrew, and Pagan authors. Written while teaching at the Santa Sabina studium provinciale, it profoundly influenced Thomistic philosophy and works like Dante's Divine Comedy. Today, it remains a key reference for those studying theology and philosophy in various Christian traditions.

A geographical map of Western Europe spans the outer ring and inner core on the right side of the coin. The inscription 2 EURO is superimposed over the map of Europe, with the numeral “2” located in an open field representing the eastern Atlantic Ocean.

12 stars are located on the right side of the outer ring, with six stars atop the map of Europe and six stars below it; six vertical stripes cut across the inner core of the coin, visually connecting the upper and lower star segments.

Luc Luycx, a designer at the Royal Belgian Mint, designed the Euro’s common reverse; his initials, LL, are seen on the right side of the design, just under the “O” in “EURO.”

The sequence "2 ★" repeated six times alternately upright and inverted
