Abstract
Abstract 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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
89 words
In a method of manufacturing coins and the like from composite material, the steps of continuously producing blanks including forming discs from the composite material, said discs each being a diameter larger than diameter of the desired finished coin, recessing the peripheral edge surface of each disc to provide peripherally extending portions on either side of the formed annular recess, bending said extending portions inwardly toward the recessed edge surface into edge-to-edge contact with each other, and marking said blanks with markings appropriate for the coin and the like.
Claim 2
Dependent Claim

In a method of manufacturing coins and the like from composite material, the steps of continuously producing blanks including forming discs from the composite material, said discs each being a diameter larger than diameter of the desired finished coin, recessing the peripheral edge surface of each disc to provide peripherally extending portions on either side of the formed annular recess, bending said extending portions inwardly toward the recessed edge surface into edge-to-edge contact with each other, and marking said blanks with markings appropriate for the coin and the like.
Claim 3
Dependent Claim
16 words
The method of claim 1, wherein the discs are punched from plated sheet or strip material.
Claim 4
Dependent Claim
20 words
The method of claim 1, wherein the recess is made in the discs by turning said disc on a lathe.
Claim 5
Dependent Claim
39 words
The method of claim 1, wherein said peripherally extending portions of the discs are folded in towards each other during rotation of said discs in one or more sequential steps bY means of pressure rollers bearing against said portions.
