1920 sixpence

[Gary D 76]

Is there a way of differentiating between the .925 silver and 0.5 silver 1920 sixpence, apart from the minute difference in weight.

Thanks, Gary

Davies only notes that the two may be distinguished by checking the "ring" by quote "placing the coin on finger tip and gently tap with a pencil. A low note indicates sterling silver and a higher one debased silver". He also notes the finish on the 0.500 silver is dull, so a comparison of a pre 1920 sixpence with a 1920 piece could also indicate which variety it is, but this would only work for a mint state example.

I would also add that the debased one may have traces of verdigris being 50% copper. Hopefully not, but it does help the I D.
