拍品描述： 1984年长城3.3盎斯的银章。官方发行量仅200枚。 通体锐打，霜面图文。<em>反面英文有误，HEROES少E。参考书上虽列明银币系列发行量是200，当中应因应铸成，打压，错体，正常款而有几款不同版别。非常有趣的一个系列，值得深究。</em>(t) CHINA. Official Great Wall 3.3 Ounce Medal, ND (1984). NGC MS-69.Cheng-pg. 26 #2. Authorized mintage of only 200 pieces. Beautifully preserved with sharply struck devices and frosty surfaces. Free of tone, haze, or fog.<em>Spelling error on the reverse with an E being omitted from HEROES. Though Cheng lists a mintage of only 200 pieces for the silver issue, it is clear that there are several different varieties for the finish, strike, spelling error and corrected spelling. An Interesting series deserving of more in depth research. </em>
