This question concerns this coin: N#2811
During the World War II years, a pair of 1 franc coins
and a pair of 2 francs coins were minted without dates on the coins.
The N-805 and N-804 coins are aluminum; the N-2421 and N-2811 coins are copper-aluminum. The coins in each pair are identical except for the alloy used to make them.
The Numista web pages for the N-805, N-2421, and N-804 coins have the following statement concerning the date the coins were minted:
"Undated coin struck in 1943 at the initiative of the Vichy government.
Those in cupro-aluminum were put in circulation only from 1945."
Numista assigns an actual minting date of 1943 to the N-805, N-2421 and N-804 coins.
The N-2811 coin, however, was assigned a 1945 actual minting date and its Numista web page lacks this statement:
"Undated coin struck in 1943 at the initiative of the Vichy government.
Those in cupro-aluminum were put in circulation only from 1945."
Question: Were all four of these coins minted in 1943, or were the aluminum coins minted in 1943 and the copper-aluminum coins minted in 1945?
The 47th edition of the SCWC assigns a date of “ND - 1943 (a)” to the aluminum N-804 and N-805 coins and a date of “ND - 1945 (a)” to the copper-aluminum N-2421 and N-2811 coins.
