ANNAM. Medallic Silver 5 Tien, ND (1916-25). NGC AU Details--Holed.
KMX-M5.1. Thin dragon variety. "Bao Chien" issue. A rather interesting and SCARCE contemporary imitation meant for wearing (hence the two holes--a common feature of the type--at the top and bottom), this piece presents very little evidence of any real usage outside of that which was intended.
Estimate: $600 - $900
