Watch List notes:

CHINESE CHOPMARKS: JAPAN: Meiji, 1867-1912, AR yen, year 28 (1895), Y-28a.5, one large Chinese merchant chopmark on obverse, gin mark to right on reverse, some light residue or light cleaning on reverse, uneven toning, AU In October 1897, Japan revalued the gold yen, and changed from a combination silver/gold standard to an exclusively gold standard. For the next six months silver yen were exchangeable for gold. Part of the demonetized silver coins were melted for use in minting subsidiary coins, and the rest were shipped to Taiwan for use as bullion silver. Before being exported, they were countermarked with the character for silver (gin), in a circle, to prevent them from being returned to Japan for another shot at exchange for gold. The gin countermark appears in a specific position - to the left or right of the ichi (one) character on the reverse. Krause states that the main Mint at Osaka applied the mark on the left side, and the subsidiary Tokyo Mint applied it to the right.
