安南明命通宝七钱。 ANNAM. 7 Tien, ND (1820-41). Minh Mang. NGC AU-55. 大致呈钢铁灰色,经手轻微,铸打颇清晰利落,原汁原味。局部可见深色包浆,但无损整体美观。 KM-191; Sch-181B. A mostly steely gray example, this lightly handled crown features a fairly clear and crisp strike, with tremendous detail and originality remaining. Some areas of darker toning are observed, but do not distract from the stunning ocular display that is put forward.
