A method in the manufacture of coins, medals and like objects from plated material, the method including the steps of forming from the plated material discs having an extension which exceeds the extension of the blanks used in the embossing operation, recessing the peripheral edge surface of each disc so that the outer layer of the disc projects beyond the central layer thereof, folding the outwardly projecting portions of the outer layers of each disc toward each other, the recess being made sufficiently large so that the said inwardly folded portions at least approximately reach each other, and embossing the resulting blanks to form coins or like objects. |
