[1911 shilling]

Agree with Nick #5: the hollow neck variety has a clear short "trough"/depression running up the back of the neck above the BM, clear even on quite worn coins as the depression is usually darker. If in doubt, easy to compare with 1912 onwards.

That's very clear and helpful- thanks Declan. All three of mine are Rev E. :-(

[1914 florin]

I'm struggling to see tooth-size variation in my early GV florins, for which 1914 apparently has two types.

Looking through 1911 to 1919, I think I see a subtle change (small teeth pre-1914; large teeth post-1914), but I'm not convinced! Can anyone help? Alternatively, is one of the 1914 types completely novel, and all other years the same?

[1844 AANNO edge error crown - unrecorded variety]

I have a 1844 (cinquefoil stops) with "ANANO". Maybe these edge mistrikes are too frequent and variable to detail as varieties?
