Chingford Posted December 17, 2017 Posted December 17, 2017 Pyx Trials - Checking precious metal coinage for weight etc... usually 50 around examples of each coin minted are checked by a select panel for conformity to size, weight, purity 1 Quote

Rob Posted December 17, 2017 Posted December 17, 2017 COA is certificate of authenticity. Surprisingly they still do a pyx trial to this day. In the days of hammered coins, even though standards were laid down, it was accepted that this constituted an average of what was capable of being produced, so the standard also allowed for a deviation in weight from it within reason and as specified. That is why a small number of coins from each batch were put into a sealed box, then at the time of changeover to the new initial mark, some coins were taken from the box, weighed and assayed. The mint master being held responsible for any failure to follow the standard. This was done to dissuade the workers at the mint from striking coin light and pocketing the difference. The reports are very useful as they specify what denominations were present at the trial, and hence we know what was issued at any particular time. Quote
