Post #8:
The Last Cast
or
Honey, I Shrunk The Coins
As described in my parallel thread on the piastre, the 1930s may have had more drama to it in the high end silver based economy. There were a few developments in the low end copper economy as well, though.
1 centième, French Indochina, 1938. Bronze, 5.0 g, 26 mm.

The first coin, however, does not show much development, it looks exactly like the 1900 coin presented in post #5. Only smaller - 5.0 g instead of 7.5 g. The shrink took place already in 1908. Better, or at least alternative, uses for the copper were available already back then. The design is the same, this coin was minted until 1939.
½ centième, French Indochina, 1939. Bronze, 4.0 g, 21 mm.

The ½ cent(ième) was a new denomination, minted 1935-40, and even smaller than the shrunk 1 cent of course. It filled a gap in the colonial denomination range, after the French sapèques of 1902 and 1905 - with a value of 1/5 respectively 1/6 cent - had been demonetized in the early 1930s. The local Vietnamese cash coins were there, of course - some of them even minted by the French authorities - but they were not part of the official economy. The depression of the 1930s also reached Indochina and there was an increased need for small values. This was France's way of marking a financial presence also at the very low end of daily transactions.
The design looks familiar, if you recall the French 25 centimes coin I showed in post #5. Those coins were minted until 1937, and this ½ cent is simply a copy of that design, hole and all. The text on the reverse has been changed, and the original olive branches have been replaced with rice stalks. It is interesting that the Chinese inscription is gone on the ½ cent while it remains on the 1 cent coin. Did the French authorities expect everyone to have learnt French by now, or did they just not care any longer?
The local cash coins
Anyhow, the local cash coins were still around. As late as 1926 (possibly later), the new emperor Bao Dai cast cash coins with his name and the usual thông bao. These are in fact the last cast cash coins, anywhere. China had abandoned the technique long ago, but the Vietnamese cherished the tradition. It could of course have been an element of silent protest against the colonial power in sticking with the traditional Vietnamese coins.
Cast cash coin, Vietnam/Dai Nam, emperor Bao Dai, 1926? Copper alloy, 3.4 g, 24 mm.

Like for the previous emperor Khai Dinh, the French authorities also struck cash coins for Bao Dai. This was done in 1933. They had the same design as the cast ones, but were considerably smaller (and were of course not liked by the locals).
Struck cash coin, Vietnam/Dai Nam, emperor Bao Dai, 1933. Brass, 1.4 g, 18 mm.

The mechanical workshop employed in 1921 for the striking of cash coins for Khai Dinh was still around, but the cost for manufacturing those coins had been high. Alternative options were sought out, and the commission landed with another Haiphong firm, Poinsard & Veyret. Poinsard & Veyret was a factory with various operations. In their own words, they made "furniture, paints, coins" among other things. They had a machine suitable for manufacturing coins by punching them from a sheet of brass, see picture below. Not a new method for striking coins for sure, but maybe the only time it has been employed to make cash coins? It was cheap and efficient but had its shortfalls. The coins near the edges tended to be weakly struck and slightly bent. They had to be manually checked and straightened with a light mallet.

As mentioned, the reception was tepid. One can understand that when placing the new, small coin next to a cast one (including also a coin struck for Khai Dinh):

Struck Khai Dinh cash (1921-22), cast Bao Dai cash (ca 1926), struck Bao Dai cash (1933).

The next and last post will look at the coinage during World War 2.
