The Historical Significance of Meiji 5 Gold Coins: The Birth Year of 'Yen'
Meiji 5 (1872) is a monumental year in Japanese currency history. Following the new currency laws promulgated in Meiji 4 (1871), a new decimal currency system called 'yen-sen-rin' was established, and the first gold coins bearing the Meiji 5 inscription were minted at the Osaka Mint as part of the old yen series. This gold coin with the inscription 'Meiji 5' is a commemorative first piece of Japan's modern unified currency system, comparable to the Imperial and metric systems. Before the issuance of the Meiji 5 gold coin, Japan's currency system was a jumble of koban, mameitagin, ichibugin, and isshu-gin from the Edo period, causing significant inconvenience and confusion in trade. The new currency regulations aimed to unify this by issuing gold coins that adhered to international currency standards under the gold standard. An in-depth exploration of the history of modern coinage can be found at Introduction to Modern Gold and Silver Coins (Meiji to Showa).
The Five Types of Old Gold Coins: The Lineup of Meiji 5 Inscriptions
There are five types of old gold coins minted at the Osaka Mint in Meiji 5 (1872). The main specifications for each denomination are as follows. Old 20 yen gold coin: Diameter 35.1mm, weight 33.33g, gold fineness 900/1000. Pure gold content 30.0g. Old 10 yen gold coin: Diameter 29.4mm, weight 16.67g, gold fineness 900/1000. Pure gold content 15.0g. Old 5 yen gold coin: Diameter 23.6mm, weight 8.33g, gold fineness 900/1000. Pure gold content 7.5g. Old 2 yen gold coin: Diameter 17.6mm, weight 3.33g, gold fineness 900/1000. Pure gold content 3.0g. Old 1 yen gold coin: Diameter 13.5mm, weight 1.67g, gold fineness 900/1000. Pure gold content 1.5g. All five types feature a unified design with a dragon pattern (ryu-mon) and the inscription '大日本・明治五年' on the obverse, and a denomination of '○圓' and the chrysanthemum crest (kiku-ka mon) on the reverse. The intricacy of this dragon pattern is a testament to the minting technology of the early Meiji period and is highly regarded as a work of art.

First Year Issue Premium: Why Collectors Target Meiji 5
The 'First Year Issue' refers to a coin from the first year of minting in a series, and it is universally highly regarded in coin collections worldwide. In the case of Meiji 5 gold coins, the historical significance lies in its inscription marking the birth year of Japan's modern currency, 'yen.' According to the databases of international coin grading institutions like PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Corporation), the Meiji 5 inscription is tracked separately from other year marks, and high-grade pieces (MS64 and above) are in demand by collectors both domestically and internationally. The market valuation of Meiji gold coins is detailed at Types and Values of Meiji Gold Coins. The rarity of being the 'First Year Issue' and its engraved historical value indicative of the Meiji government's drive for modernization supports a strong collector demand.
The Value of Rare Denominations: Why Old 2 Yen and Old 1 Yen are Exceptionally High
Among the five types of Meiji 5 gold coins, the old 2 yen and old 1 yen gold coins boast exceptional rarity. This is due to the number of minted coins. While about 460,000 old 20 yen gold coins with the Meiji 5 inscription were minted, it is estimated that only a few thousand old 2 yen coins and a few hundred old 1 yen coins were produced. This stark difference in minting numbers reflects their varied roles within the currency system. Large denominations like 20 yen and 10 yen were used for international trade and large transactions, while the smaller, less practical 2 yen and 1 yen were minimally produced. The factors determining the value of old coins can be explored at Factors Determining the Value of Old Coins. Individual prices and auction results are listed only once verifiably matched records — with sale, lot, source URL and review date — exist.
Authentication and Counterfeit Coin Measures
Due to the high transaction value of Meiji 5 gold coins, a certain number of skilled counterfeits are in circulation. It is crucial to understand basic authentication points. First, weight measurement is vital. Each denomination's standard weight (old 20 yen = 33.33g, old 10 yen = 16.67g, etc.) should be checked with a precision scale, requiring detailed inspection if there's a deviation of over 0.3g. Second, inspect the edges. Genuine old coins have evenly spaced serrations (glue) on the edge, while counterfeits may lack this uniformity. Third, examine the intricacy of the dragon pattern. Authentic old coins have scales and claws clearly carved individually, whereas on cast copies, these details become ambiguous. For secure purchases, selecting coins graded by PCGS or NGC or buying from specialists affiliated with the JNDA (Japan Numismatic Dealers Association) is recommended. Detailed guidance on identifying counterfeit coins is available at Complete Guide to Spotting Fakes and Altered Coins.
International Recognition and Utilization of PCGS/NGC Slabs
Meiji 5 gold coins have recently garnered attention from international coin investors. Encasing them in PCGS or NGC slabs provides protection, authentication, and grading certification, thereby significantly enhancing their liquidity in the international sales market (such as overseas auction houses and eBay). Particularly, wealthy collectors in Hong Kong, Singapore, and Taiwan, as well as Western collectors with a keen interest in Japanese culture, show strong interest in Meiji gold coins. Graded high-quality pieces (MS65 and above) of the Meiji 5 inscription often fetch higher prices at overseas auctions compared to the domestic market, thanks to the premium value attributed to the 'birth year of yen' narrative. The market of Taisho-era silver coins can also be referenced at The Market of Taisho Silver Coins.
Acquisition Methods and Collector's Practical Guide
Acquiring Meiji 5 gold coins requires caution due to their rarity and high value. A highly reliable acquisition routes are direct consultations with established domestic old coin specialists (JNDA members) and participation in major old coin auctions. Ultra-rare coins like old 2 yen and old 1 yen coins can only be acquired by waiting for auction listings, which occur 1-2 times a year, necessitating registration with major auction house mailing lists to avoid missing opportunities. Starting a collection with more easily obtainable denominations like old 5 yen and above, gaining insight into market trends and price perceptions, before venturing into rare denominations is a wise approach. Additionally, conducting weight measurements and consulting experts before purchases helps minimize the risk of buying counterfeits. A foundation in utilizing old coin auctions is covered in Introduction and Utilization of Old Coin Auctions. Gold coins engraved with the special year of Meiji 5 are supreme historical materials telling the story of Japan's modern history and are attractive acquisition targets from a long-term value preservation perspective.
