Hi!
After a quick browse in the South Vietnam catalogue, I realised two "countries" have been mixed together. These are the State of Vietnam (Quốc gia Việt Nam) (1949-1955), which includes the whole modern day Vietnam, and Republic of Vietnam (aka South Vietnam) (Việt-Nam Cộng-Hòa) (1955-1975).
I can only assume this is an error which just never has been corrected. State of Vietnam should, obviously, be catalogued seperately from South Vietnam. Maybe as a sub-issuer of Vietnam?
The coins that needs to be move to the new State of Vietnam are:
10 Su - Bảo Đại
10 Su - Bảo Đại (Essai)
10 Su - Bảo Đại (Piefort Essai)
20 Su - Bảo Đại
20 Su - Bảo Đại (Essai)
20 Su - Bảo Đại (Piefort Essai)
50 Xu - Bảo Đại
50 Xu - Bảo Đại (Essai)
50 Xu - Bảo Đại (Piefort Essai)
Thank you!
