Once fired, PMC can be hallmarked as Fine Silver .999.

By law if you plan to sell your PMC items a hallmark is required if the piece weighs more than 1 gram for Gold and 7.78 grams for Silver. Anyone can submit items for hallmarking but there is usually a standard fee so the more pieces you can send to be hallmarked at a time, the better.

There are 4 Assay offices in the UK: Birmingham, Edinburgh, London, Sheffield
