| Obverse description | Cast copper cash coin of the Joseon dynasty featuring the standard four-character legend 常平通寶 (Sangpyeong Tongbo) arranged in cruciform fashion around a central square hole, reading top-bottom-left-right in the traditional manner. The characters are rendered in regular script (kaishu) in raised relief against a flat field, enclosed within a raised inner square rim and a plain outer rim. The overall design follows the conventions of East Asian cast coinage, with no additional decorative elements in the field. |

All characters and symbols are cast in raised relief within the standard raised inner and outer rims typical of Joseon-period cash coinage. |

| Additional information |
The "Cold" designation — a translation of the Korean 冷 (naeng) — refers to coins cast at furnaces operating at lower temperatures, a distinction the Joseon monetary authorities used to differentiate output quality across the numerous provincial and military casting bureaus authorized to produce 2 Mun coinage in the 1740s. Joseon never operated a centralized mint in the Western sense; casting rights were distributed across government offices, temples, and military commands, each producing to their own tolerances.
KM#671 is one of dozens of catalogued varieties from this period, distinguished by furnace designation rather than issuing office alone.
