The 1946 "dot" is the least dot-like of all these features and, on an uncirculated example can be seen as just a lump of clag. See below 1946 F233 ONE' Flaw zoom.JPG I have a 1946 Dot like yours, but I also have a CGS Slabbed 1946, with almost a perfect "Dot"...pic attached. 1946 Dot close up.jpg Now that is very interesting - your dot appears to be in a different place, a little nearer to the E !! My "dot" is far from circular and matches the picture in Michael Gouby's book "The British Bronze Penny 1860 - 1967". It also matches 2 spares that I have which are more worn, with the "dot" becoming more like a dot as it wears down. Could you post a pic of the whole reverse to compare positions. I'll post pictures of the spares.
