I have looked for many years for the date(s) of shipment for the 10 and 20 Cents 1941-S copper-nickel coins minted at the San Francisco Mint for French Indochina. By the end of July 1941, the Japanese were in military control of French Indochina so I am thinking the shipment was before that time. But the United States was already working on stopping shipments of important metals to Japan, so why allow millions of copper-nickel coins to be shipped to French Indochina where the Japanese could confiscate them? If anyone knows the date(s) of shipment of these coins, please contact me at HADaniel3@msn.com.
