Sorry for dragging up an old post. Looks like this was from the reign of Minh Mang, 1820 -1841? Here are a couple of cash from that time, one copper, the second zinc.
50 su 1960, aluminium, weight - 4 g., size - 30,75 mm, thickness - 2,7 mm, mintage - 10000000 pcs. Engraver: Norman Sillman. Single release.
South Vietnam. 1 dong 1964, copper-nickel, weight - 3?95 g., size - 22,3 mm, thickness - 1,3 mm, mintage - 190000000 pcs. Single release.
South Vietnam. 1 dong 1960, copper-nickel, weight - 3,6 g., size - 22 mm, thickness - 1,3 mm, mintage - 105000000 pcs. Engraver: Norman Sillman. Single release.
Another one cast with the fine craftsmanship of the Minh Mang era. This may be a forgery but if it is, it is well done. Barker 144.
Liberation dong (1975-1978). 2 xu 1975, aluminium, weight - 1,1 g., size - 21 mm, thickness - 1,5 mm, mintage unknown. Single release.
Liberation dong (1975-1978). 5 xu (1975), aluminium, weight - 1,5 g., size - 23 mm, thickness - 1,6 mm, mintage unknown. Single release. Such coins were released after the liberation of South Vietnam and circulated at 1975-78. The liberation dong was exchanged for the dong of South Vietnam (Republic of Vietnam) at the rate of 1 to 500. In 1978, the liberation dong was withdrawn from circulation, completely replaced by the dong of the Socialist Republic of Vietnam (at the rate of 0.8 SRV dong for 1 liberation dong). There were only 3 types of coins issued: 1, 2 and 5 xu. All of them are among the infrequent.
State of Vietnam. 50 xu 1953, aluminium, weight - 3,5 g., size - 31 mm, mintage - 15000000 pcs. Engraver: Lucien Georges Bazor. Paris Mint. Single release.
It only has one singular/solitary meaning for me and too many of my other American Army/military buddies circa 1965-1975...that meaning will NEVER change and guarantee you don't want to read it. Post the coins but leave the rest.
Sorry. I respect your position. But these coins were really called "Liberation" dong. Coins from South Vietnam – Numista
