Tu Duc gold Tien ND (1847-83) AU58 NGC, KM-Unl, Fr-Unl, cf. Schroeder-354 (in silver). 24mm/3.48g. An engaging issue in gold that features Tu Duc Thong Bao in Han-nom characters surrounding a central hole and two fish swimming downstream, with Nhat Duc above and below. Attractive, coppery-red color traces the devices and wear is essentially negligible. Exceedingly rare and quite possibly unique in gold, with none of the specialized references offering any additional information.
Estimate: 6000-8000 USD
