1987年1元内蒙古自治区成立 40 週年精制币。 内蒙古自治区成立四十周年纪念。<strong>非常罕见</strong>，动人的样币版，在市场上几乎绝迹。图文极緻霜化，镜面底板锃亮，浮雕效果出衆。边缘有棕香槟色氧化，更具独特魅力。
CHINA. Yuan, 1987. NGC PROOF-69 Ultra Cameo. KM-187. Celebrating the 40th anniversary of the Mongolian Autonomous Region, this <strong>VERY RARE</strong> and enticing proof version is seemingly never available on the market. Supremely frosted devices combine majestically with exceptionally mirrored fields, ultimately creating a great cameo nature. A hint of burnished champagne toning at the peripheries adds even further charm and character.
