Seldom Offered Tempo-Era Goryoban JAPAN. Goryoban (5 Ryo), ND (1837-43). Tempo. PCGS AU-50 Gold Shield. Fr-8; JNDA-09-12; KM-C-23. Mintage: 172,275. A neat short lived multiple-Ryo denomination produced only a few years and seldom appears on the market. The stamps are well applied, crisp and nicely defined with frosty fields. A tenderly handled and well preserved representative of the type with a nice original skin. An attractive example with lovely orange hued golden patina throughout quite pleasing to the eye sure to entice serious consideration from advanced Japanese collectors. Another aspect of historical context, on 31 March 1854 Commodore Perry negotiated a trade agreement with Japan. This first trade agreement wasn't so advantageous for foreigners and mostly favored the local Japanese with an exchange rate of 1:1 United States Dollar to Japanese Ichi bu (which was worth about 0.34 cents). This lasted more that five years until on 29 July 1858, Mr. Townsend Harris, First Consul-General of the United States of America to Japan negotiated a new trade agreement fixing the exchange rate and setting a new medium of exchange the "Mexican Dollar". The new treaty was to come into full effect 4 July 1859 and in total favor of the United States. The new exchange rate was 1:3 Mexican Dollar to Japanese Ichi bu. Once the agreement came into full effect Japan experienced a mass exodus of gold coins with a ratio of 4:1 Japanese Ichi bu to gold Koban, worth twelve Mexican Dollars outside of Japan. Since the opening of the Japan many large gold coins such as Kobans, Obans and Goryobans began leaving the country as they commanded a 70% profit outside the country. This could account for their scarcity in today's market. Estimate: $8,000 - $12,000. Click here for certification details from PCGS.
