I received a response from the Royal Mint today, as follows: Thank you for your enquiry of 26 January. Your Royal Mint token is an obsolete pass-out check used by the industrial staff at the old mint at Tower Hill in London between 1925 and 1945. The system is explained by the attached Office Notice of 4 July 1925 and as you will see a distinguishing letter was used for each of the rooms or sections of the factory. In the case of your specimen the distinguishing letter is the ‘L’ which relates to what was known as the Inland Revenue Department where postage embossing dies, dating plugs and plates for stamps were made. But we can offer no explanation for the incuse letter ‘W’. We do have one of these pass-out checks in the Royal Mint collection. It bears the distinguishing letter ‘A’ to denote the Melting House but there is no incuse letter. If you ever decide to dispose of your specimen, you might like to think of us as we would be interested in obtaining additional examples. With respect to the other piece, we are inclined to think from the photographs that this is not a brockage and, indeed, does not emanate from the Royal Mint. Yours sincerely Joseph Payne Assistant Curator The Royal Mint Page 1 of Office Notice Page 2 of Office Notice
