Coins from South Korea: Identification & Value Guide
Coins from South Korea range from common modern won issues to pieces like the Joseon "mun" cash coins that serious collectors compete for. This guide covers how to identify South Korean coins, which issues are genuinely collectible, and what realistic values look like today.
A short history of South Korean coinage
Korea’s traditional money was the cast bronze "mun" cash coin with a square central hole, much like China’s, circulating for centuries under the Joseon dynasty. Modern machine-struck coinage arrived in the late 19th century as Korea opened to the world, briefly producing yang and won before Japanese annexation interrupted independent coinage.
The Republic of Korea (South Korea) issued the hwan and then, from 1962, the won that remains its currency. Modern won coins carry cultural and natural motifs — Admiral Yi Sun-sin, the rose of Sharon, a crane, rice stalks — struck by the Korea Minting Corporation (KOMSCO).
How to identify coins from South Korea
Most South Korean coins can be pinned down in a minute or two once you know the tell-tale signs. Check the inscriptions first, then work through the symbols, portraits and dating conventions:
- Korean (Hangul) script and the denomination in won identify modern South Korean coins.
- Cultural figures and symbols — Admiral Yi Sun-sin, the crane, rice, the rose of Sharon — feature on the reverses.
- Old cast "mun" coins are round with a square central hole and Chinese-character (Hanja) legends.
- Late-19th-century transitional coinage may carry dragons and mixed Korean/Chinese legends.
- Modern coins are dated with Western years in Arabic numerals.
The most collectible South Korean coins
If you are checking a group of South Korean coins for better pieces, start with these — the dates and types with a proven collector following:
- Joseon "mun" cash coins — Cast bronze holed coins of old Korea, mostly inexpensive.
- Late-19th-century yang/won — Scarce transitional machine-struck coinage as Korea modernised — often valuable.
- Early republican hwan/won — First coins of modern South Korea, collectable in high grade.
- KOMSCO commemoratives — Modern proof and commemorative issues, including popular themed coins.
What are South Korean coins worth?
Scarce late-19th-century Korean machine-struck coinage can be genuinely valuable, and old cash coins are affordable. Early republican coins are collectable in high grade, while modern base-metal won circulation coins are largely face value. The short, disrupted history of independent Korean coinage makes early modern pieces relatively scarce.
As always in numismatics, grade multiplies value: the same coin can be worth small change worn flat and a strong premium in uncirculated condition, and genuinely rare dates rewrite the math entirely. The most honest benchmark is what comparable coins actually sold for. As a starting point, AI Coin Collector shows the Numista catalogue price per grade for every South Korean coin it identifies.

Frequently asked questions
How do I identify a coin from South Korea?
Korean (Hangul) script and the denomination in won identify modern South Korean coins. Add the date, denomination and any mint mark and you can usually narrow it down to an exact catalog type — or photograph it with AI Coin Collector for a quick suggested attribution.
Are old South Korean coins valuable?
Scarce transitional coins from Korea’s late-19th-century modernisation can be valuable, while old cash coins and modern base-metal won are inexpensive or face value. Early republican coins are collectable in high grade — exact identification is key given the short, disrupted history.
What are the old Korean coins with a square hole?
Those are "mun" cash coins, cast in bronze with a square central hole and Chinese-character (Hanja) legends, used in Korea for centuries under the Joseon dynasty — the Korean equivalent of Chinese and Japanese cash coinage. Most are inexpensive, though rare types and mints carry premiums.
Can AI Coin Collector recognize South Korean coins?
Yes. Photograph the coin and AI Coin Collector identifies it using our own AI vision model, estimates its grade on the Sheldon 1–70 scale, and shows the Numista catalogue price per grade.
