1 oz Zi:Sin Silver Round

South Korea's Twelve Guardians in Silver

The 1 oz KOMSCO Zi:Sin silver round is part of a 12-piece series from South Korea's sovereign mint, each annual release depicting one of the Sipijishin (Twelve Guardians) from Korean mythology. These divine commanders protect against evil from twelve directional points, aligned with the Korean lunar calendar's 12-year animal cycle. The series launched in 2017 with Gallus (Rooster) and completes in 2028 with Pithecus (Monkey).

KOMSCO (Korea Minting, Security Printing and ID Card Operating Corporation) is the official government mint of South Korea, established in 1951 and headquartered in Daejeon. Despite being a sovereign mint, the Zi:Sin pieces are classified as medals rather than coins, denominated in "Clay," a non-circulating monetary unit created specifically for KOMSCO's bullion programme. This distinction affects tax treatment in some jurisdictions, particularly regarding IRA eligibility in the United States.

The series shares its obverse Dokkaebi shield design with KOMSCO's other bullion range, the Chiwoo Cheonwang. Annual silver mintages range from 20,000 to 40,000, placing the Zi:Sin firmly between mass-market sovereign coins (millions of pieces) and ultra-limited collectibles. Early years with lower mintages, particularly the 2020 Rattus (22,000) and 2021 Taurus (20,000), command notable secondary market premiums.

For buyers seeking Asian-themed silver with genuine mythological depth and lower mintages than the dominant Perth Mint Lunar series, the Zi:Sin occupies a distinctive niche. The defined 12-year endpoint gives collectors a clear finish line, unlike open-ended annual series that run indefinitely.

Annual Mintage Figures

A latent security element on the obverse displays "999" and KOMSCO branding when tilted at specific angles. Packaging follows standard bullion conventions: individual plastic flips, mint tubes of 25, and sealed boxes of 250.

Tax Considerations for KOMSCO Medals

The Zi:Sin's classification as a medal rather than a legal tender coin creates specific tax implications. The "Clay" denomination is a KOMSCO-created unit for its bullion programme and does not circulate as currency in South Korea (which uses the Won).

United Kingdom

Silver medals attract the full 20% VAT on purchase. No CGT exemption applies (reserved for UK legal tender coins only). The medal classification makes no practical difference to UK tax treatment compared to other 1 oz silver rounds, as all non-legal-tender silver products face the same 20% VAT.

United States

State sales tax treatment varies. Approximately 35 states exempt bullion from sales tax. The more significant issue is IRA eligibility: most Self-Directed IRA custodians require sovereign legal tender coins for precious metals holdings. The Clay denomination may not satisfy this requirement, making the Zi:Sin unlikely to qualify for tax-advantaged retirement accounts. Capital gains are taxed at the 28% collectibles rate for holdings exceeding one year.

Canada

GST/HST exempt at 99.9%+ purity. The .999 silver content qualifies the Zi:Sin for this exemption regardless of its medal status. Canadian tax law focuses on metal purity and form (bar, ingot, coin, or wafer), and medals meeting the purity threshold are treated equivalently.

Singapore and Hong Kong

Singapore exempts Investment Precious Metals (IPM) at 99.9% silver purity from GST. The Zi:Sin meets the purity requirement. Hong Kong has no sales tax or capital gains tax, making it entirely tax-neutral for bullion of any classification.

European Union

Standard VAT rates (17-27% depending on country) apply to silver medals. No investment silver exemption exists for non-EU legal tender products. The German Differenzbesteuerung (margin scheme) applies only to pre-owned coins, not new medals.

The Twelve Guardians of Korean Mythology

The Sipijishin (Twelve Guardians) depicted on each Zi:Sin release are divine commanders carved into stone at the UNESCO World Heritage site of Seokguram Grotto near Gyeongju, dating to the 8th century. These warrior figures stand guard at twelve directional points, each wielding signature weapons and possessing supernatural abilities including summoning wind and rain, transformation, and warding off demons. The coin series draws directly from this centuries-old Korean artistic tradition.

KOMSCO launched the series in 2017 with Gallus, the Rooster guardian described as a "messenger of light" capable of summoning solar-bright illumination and foreseeing future events. The series was conceived as a companion to the Chiwoo Cheonwang range (launched 2016), which features the Korean God of War annually. Both share the Dokkaebi obverse shield, creating a visual family across KOMSCO's bullion programme.

The Dokkaebi (dokkaebi) on the common obverse is itself a significant figure in Korean folklore: a mythical guardian spirit that wards off evil, comparable in cultural function to a gargoyle in Western architecture. The shield is quartered and bears KOMSCO's hallmarks alongside the year, purity, denomination, and weight.

Mintage varied significantly across the series. The initial years (2018-2019) produced 40,000 pieces each, then dropped sharply to 22,000 (2020 Rattus) and 20,000 (2021 Taurus) before stabilising at 30,000 from 2022 onward. The low-mintage middle years now command secondary market premiums above later releases. Gold versions at approximately 1,200 pieces per year are exceptionally scarce for a government-backed bullion product. Special editions of the 2019 Scrofa included Eclipse (1,000 mintage), Hybrid (500), and various plated variants at 333 pieces each.

Zi:Sin Against Other Asian-Themed Silver

The most direct competitor is KOMSCO's own Chiwoo Cheonwang series, which shares the same mint, obverse shield design, Clay denomination, and 40 mm diameter. The Chiwoo features a single recurring character (the God of War) each year with design variations, making it a more unified collection. The Zi:Sin rotates through 12 distinct guardian figures, providing greater variety but requiring collectors to acquire different designs each year. The Chiwoo launched one year earlier and has stronger name recognition in the secondary market.

Against the Perth Mint Lunar Series III, the differences are substantial. The Perth Lunar uses Chinese zodiac animals in .9999 silver with mintages in the hundreds of thousands, prioritising liquidity and wide availability over scarcity. The Zi:Sin offers Korean mythology with mintages of 20,000-40,000, a fraction of the Perth output. Perth coins carry Australian legal tender status with face values in AUD, giving them broader acceptance and clearer IRA eligibility. The trade-off is that Perth Lunar premiums are lower on the primary market but the secondary market advantage is smaller.

The Royal Mint and Royal Canadian Mint both produce Chinese Lunar series as well, further saturating the 12-animal-cycle category. The Zi:Sin's Korean mythological angle, with warrior guardians rather than simple animal depictions, distinguishes it from all three competitors thematically.

The 1 oz Germania Mint Witchcraft round offers a different comparison point for buyers seeking mythology-themed private mint silver. Germania's .9999 purity and octagonal shape differ from the Zi:Sin's .999 purity and standard round format, but both operate in the limited-mintage thematic silver space at similar price points.
