About Ansei Chogin Purchase (GoldSilverJapan)

GoldSilverJapan purchases Ansei Chogin, issued during the late Edo period. Ansei Chogin is one of Japan's representative antique gold and silver weighing coins, with a long, slender "sea cucumber shape" that differs significantly from current round coins. As a silver coin circulated during the crucial period of the late Edo period in Japanese history, it possesses not only material value in the silver itself, but also historical value as Edo currency and collector value in the antique coin market. At GoldSilverJapan, we don't simply evaluate based on weight alone; we comprehensively assess the coin after considering silver purity, weight, markings, shape, condition, authenticity, and domestic and international market trends. Because Ansei Chogin coins vary in weight and shape from one piece to another, it's crucial to examine the unique characteristics of each coin, including larger pieces weighing around 167.8g.

What is Ansei Chogin? – Silver Coins Used by Weight in the Edo Period

Ansei Chogin coins represent the silver currency system of the Edo Shogunate during the late Edo period. Unlike modern systems where all currency has a fixed weight and face value, such as 100-yen and 500-yen coins, the Edo period long utilized a system of weighed currency where the value of silver coins was determined by their weight. Chogin coins are a prime example of this system, used in transactions along with Mameitagin coins, where their weight was measured before use. Therefore, no two Chogin coins are exactly alike in shape or weight. They vary in length (long and slender), width (wide), and weight (heavy), and there are individual differences in the position and persistence of the dies. This characteristic of "each coin being different" is the charm of Chogin coins, something not found in modern machine-made currency. At GoldSilverJapan, we consider this aspect of Chogin as a historical document that conveys the Edo period's monetary system itself when conducting appraisals.


How we determine the purchase price – valuing it not just by weight, but as a historical coin

Ansei Chogin coins are primarily made of silver, so the price of silver and weight are important factors in the appraisal. However, their value is not simply determined by weight multiplied by the price of silver. At GoldSilverJapan, we comprehensively examine weight, silver purity, the condition of the markings, overall shape, the condition of both sides, wear, discoloration, presence of processing or repairs, authenticity, demand in the domestic antique coin market, demand for Japanese antique gold and silver overseas, and past auction transactions. In particular, coins with relatively clear markings, good overall shape, those that haven't been excessively cleaned or polished, and those that retain their historical patina may receive a higher market valuation as antique coins. Furthermore, the weight itself is a characteristic of each Chogin coin, so even heavy coins like 167.8g will be evaluated after physically inspecting them. The final purchase price will be determined based on the price of silver at the time of appraisal and the state of the antique coin market.


Regarding the Markings, Shape, and Condition

When appraising Ansei Chogin (silver coins), the markings (gokuin) on the surface are one of the important points to check. Chogin coins have multiple markings, and their arrangement, the remaining characters, and the degree of wear are examined. However, since these are coins actually used during the Edo period, wear, scratches, and discoloration are not uncommon. Even if there are natural tones such as silver-gray, black, or reddish-brown, as well as fine scratches, unevenness, spots, deposits, and wear on the markings, appraisal is still possible. With old silver coins, forcibly polishing or cleaning with chemicals can cause the historical surface condition to be lost, potentially affecting their value in the antique coin market. Therefore, if you are considering selling, we recommend submitting them for appraisal in their original condition without polishing. Don't assume they are worthless because they are discolored or unsellable because they are scratched; please send us photos first.


The Historical Value of Ansei Chogin in Late Edo Period Japan

The Ansei period spanned from 1854 to 1860, a time when Japan began to move significantly from its long period of isolation during the Edo period to the international community. The opening of the country, trade with foreign nations, and issues surrounding the gold-silver exchange rate marked a major turning point in Japan's monetary system. Ansei Chogin coins are ancient silver coins that convey the monetary culture of this turbulent period to the present day. Later, Japan entered the Meiji era, transitioning to a modern monetary system based on yen, sen, and rin. In this sense, Ansei Chogin coins symbolize the end of the long-lasting weighed silver coin system of the Edo period. Along with koban, ichibukin, ichibugin, nishugin, and mameitagin, they are in demand from collectors systematically collecting Japanese monetary history. Furthermore, Edo period coins are sometimes collected overseas under names such as "Edo Period Coin," "Samurai Coin," and "Japanese Chogin," making the international collector market a useful reference point when appraising them.

Q2. Can you appraise Ansei Chogin coins even if their weight differs (e.g., 167g or 170g)?

Yes. Chogin coins are weighed coins, unlike modern fixed-value currency, and their weight and shape vary from coin to coin. We do not judge authenticity or value based solely on weight; we comprehensively check the markings, shape, material, and condition.

Q3. Are Ansei Chogin coins purchased based solely on their silver value?

No. While the material value of silver is one factor in the appraisal, Ansei Chogin coins have a collector market as antique gold and silver from the Edo period. We comprehensively evaluate authenticity, markings, condition, weight, shape, and domestic and international demand.

Q4. My coin is tarnished or discolored. Should I polish it before appraisal?
