I am delighted to say that I have managed to get this page working again, with thanks to Bob Johnson who had helped me with the first version. It went wrong again early in 2013 because of changes by Google, and it went wrong again early in 2014 thanks to changes at Google, and again further work was needed to get it visible. It went wrong yet again in 2017 as Google deleted the original file.It went wrong yet again because of changes in the website containing the data, and Google again closing my access and I hope it is now working more reliably.
Please bear in mind that these values are offered as a guide and that I can take no responsibility for their accuracy or otherwise.
If you cannot see any details above, I regret to say that you need a more modern browser or there has been another change out of my control. Slightly dated information can be found here (I shall update the page occasionally).
The silver threepence is half the weight of a sixpence, but remember that the
percentage weight loss due to wear is higher (400 threepence are
generally less heavy than the same face value (40) of halfcrowns).
The crown and double florin are twice the weight of the halfcrown and
florin respectively. However, these pre-1946 silver coins almost always have a numismatic
value in excess of their bullion value.
