METHOD OF DECORATIVE MODIFICATION OF COIN SURFACES, MEDALS, TOKENS MADE OF METALS PLASTIC IN COLD DEFORMING OR THEIR ALLOYS AND PRODUCT MADE BY THIS METHOD Russian patent published in 2012 - IPC A44C21/00 

FIELD: personal use articles.

SUBSTANCE: method of decorative modification includes production of metal blank, refinement of its surface by cleaning and polishing, cold plastic deformation of the front and/or back surfaces by stamping on them of volume dull decor and adjacent to it flat mirror decor contrasting by class of texture and tone. The stamping of decors is performed on the locally placed site or sites of the surface. Along with stamping the decors on the outer edges of the local sites, stamping carry of projection or projections is carried out. From the side of lateral edge of the projection, opposite the edge of the projection adjacent to the local sites of decor made by plastic deformation on the surface or in the locally placed sites of the surface of the blank a mosaic decor is made. Before installation of the mosaic decor the sites of surface with volume and flat decors contrasting by class of texture and tone are masked. The product contains on its front and/or back surfaces the volume dull and flat mirror decors which at the local site or sites of the surfaces have projection along the outer contour. From the side of lateral faces of projection opposite its faces adjacent to local sites of volume and flat decors, on the surface or at the locally placed sites of the surface of the blank the mosaic decor is located.

EFFECT: increased efficiency of the method.
