摘要：A process for producing a flat product such as a coin Includes the steps offorming a slurry comprising a suspension of particulate material in a film-forming

cellulose derivative, depositing a quantity of this slurry onto a support surface, drying theslurry to form a self-supporting flat product, and removing the dried product from thesupport surface. The particulate material essentially comprises metallic particles andmatter whose chemical composition and physical properties differ from those of themetallic particles such that the added matter is not or only partially taken into solutionwith the metallic particles on heat treatment of the product whereby the presence of theadded matter can readily be detected following such heat treatment.
