ANNAM. 4 Tien, ND (1848-83). Tu Duc. PCGS MS-63.
KM-450; Sch-Unlisted. Weight: 15.35 gms. Some minor striking weakness is noted, but this stunning example is free from issue and stands as an exceedingly wholesome and unhandled example of this broader type. Some deeper toning near the peripheries and around the devices adds even further to the character. Tied with just one other specimen for the top spot in the PCGS census.
Estimate: $2000 - $4000
