日本明治十三年二十钱银币。大阪造币厂。 发行量：96枚。赏心悦目，精製币面，惹人注目。多彩包浆内敛，虽然设计并不繁复，但美感十足。无经手痕跡，品相完好无比，放大镜下细看方见擦痕，但微乎其微。钱币史上广受追捧的一枚，要拥有此枚必先经过激烈竞夺。一旦错失，便难以再次在市场上重逢，钟情此版的藏家定為之倾心。可言曾收藏此枚的藏家寥寥无几，赢家定可為集藏锦上添花。 <em>日本钱币史上极其重要的一枚，此版仅发行过样币，与其他面值并成套组，应是赠与显要人物的礼物，但迄今為止未见完整一组。仅96枚的发行量已是极低，但是留存下来的更是微乎其微，虽实际数量未知，但极大可能多个面值合共少於 10 枚，有纪录显示上一次此枚现身市场已是数十年前。此版所属的套组通常被用来和安祖积逊在位期间发行的1804年美国精製币套组比较，两个发行精美不分，美轮美奐。
JAPAN. 20 Sen, Year 13 (1880). Osaka Mint. Mutsuhito (Meiji). NGC PROOF-62. KM-Y-24; JNDA-01-21; JC-09-21; Jacobs/Vermeule-Unlisted. Mintage: 96. This beauty demonstrates a sensational eye appeal, with the proof surfaces reaching out and grabbing the eyes of anyone who gazes upon them. Faint spectral toning bathes the surfaces, enough to affect the aesthetic judgment of even the most austere. No instances of contact abut the surfaces, leaving the proof beauty fully intact. Just a minuscule amount of friction can be evidenced under magnification, but these faint wisps are so inconspicuous as to be approaching a Zenos paradox of unimportance. As one of the most desirable pieces in the history of numismatics, it is not impossible to foresee strong and competitive bidding for this lot. With examples being so uncommon as to make it impossible to count on one ever reaching market again, one must feel extra compulsion to bid. Very few people can claim to have ever owned an example such as this one in their collection, and the winning bidder will be able to register their name amongst that lofty lot. <em>This miraculous proof only issue is among the most important issues in Japanese numismatics. Only produced for use in specimen sets, likely as gifts for dignitaries, no examples of the entire set are known to be intact, leaving only pieces of the sets dispersed. While the mintage of 96 is already low, the survival rate of these pieces is likely considerably lower. It is unknown, but it is quite possible, that less than 10 examples of several denominations exist today. Research indicates that these types come to market particularly infrequently, with only an occasional smattering offered over the course of the past few decades. Often, the entire set is compared to the 1804 United States Proof set gifted during the presidency of Andrew Jackson, with comparable elusiveness and beauty. One of the most preeminent examples in the entire bourse of Japanese numismatics, and numismatics more generally.</em></p>
