Hello everyone, For a while now I have had an 1806 farthing - fourth type from the SOHO mint - in my collection, coloured in silver. It is only now, as I have come across another, which is of the same date but from Ireland, that I wonder why this is? I have enclosed pictures and have thought of a few possible reasons: They could have been coloured to pass as other coins, such as sixpences or half guineas? They may have been coloured afterwards to be put on jewelry? It may have been accidentally done by the mint? Something to bear in mind though with both is that they look nothing like any other coins and certainly did not fool me when buying them; a sixpence has never had "Britannia" on it! Also, in Ireland as far as I am aware, gold coins were never issued so there would be no need to try passing a farthing as a half guinea. I am also looking to, if possible, get rid of the colouring. If anyone has done this before, and more importantly if it is safe, then please let me know. Thank you.
