1943, 1945, And 1946 50 Cents With Die Clashes

The George VI 50c Die Clashes are an interesting item to collect. You can find them in most years, but I have never found them for 1947 or 1948. In the years 1937 to 1942 you will find them as a faint line through rhe crown on the Reverse and as a small bud in the King's ear on the Obverse. In the years 1943 to 1946 they just have increased the strike pressure as the complete outline of the King's head can be found on the Reverse, sometimes doubled which would indicate multiple clashes of the dies. The bud in the ears is more pronounced on the Obverses and you can find spikes around the kings hair and often clash marks in front of the King's face.
1949 seems to be a transitionary year.... somet coins can be foundd with the 1943-1946 characteristics, and the later 1949 through 1952 clash marks have completely different characteristics. The Reverse Die Clashes will show as a line through the three lions section of the shield which reaches down to touch the top of the harp section of the shield. On the Obverse the clash marks in the King's ear are much busier. My belief is that when the Mint received their Janvier machine, they recontoured the King's bust on later dies and this was the cause of the difference in the Die Clash characteristiics on the later 50c die clashes and the coins.
