1 Mon 'Eirakutsūhō' Hammered gold, Reverse Omodaka

Obverse description	Round hammered gold flan with a raised inner square border framing the central square perforation. Four boldly rendered Chinese characters in regular script (kaisho) are disposed in the four cardinal positions around the central hole: 永 (ei) above, 通 (tsū) to the right, 寶 (hō) to the left, and 樂 (raku) below, together reading 永樂通寶 (Eirakutsūhō, meaning 'Eiraku Currency'). The characters are deeply struck in high relief against a plain, flat field, and the coin is encircled by a broad, plain rim typical of Japanese hammered coinage of the Sengoku period.

Reverse description	Plain hammered gold reverse featuring a raised inner square border surrounding the central square perforation, with the remainder of the field left largely blank. A small stylised omodaka (arrowhead plant, Sagittaria trifolia) motif is lightly struck in the upper field above the square hole, serving as the sole decorative element and acting as a mint or workshop mark. The broad, plain rim and generally flat, unadorned field are characteristic of Japanese hammered gold coinage of the late sixteenth century.
