초록 ▼

The present invention relates to novel metallic composites that are useful as coinage materials. These composites are produced through a multi-ply plating process and are designed to overcome difficulties associated with calibrating vending machines that can result in fraud. In one embodiment, the metallic composite comprises a steel core over which nickel and then a non-magnetic metal such as copper, brass or bronze is deposited as a layered pair. The magnetic and non-magnetic metals may also be applied in the reverse order, with the copper, brass or bronze applied directly over the steel and then covered by the nickel. The electromagnetic signature (EMS) of the composite is controlled by defining the thickness of the deposited metal layers. Advantageously, the invention overcomes problems associated when different coins are made from the same alloy and have similar sizes, and therefore cannot be distinguished by vending machines.

1. A method of producing circulation coins having different electromagnetic signatures (EMS) and having approximately identical mass and exterior dimensions, the method comprising: selecting first and second steel cores having approximately identical mass and exterior dimensions;electroplating a first layer of nickel on the first steel core;electroplating a first layer of copper over the first layer of nickel on the first steel core, the first layer of copper having a thickness of at least 4 μm, to produce a first coin having a first EMS defined by a first range of conductivity values;electroplating a second layer of nickel on the second steel core;electroplating a second layer of copper over the second layer of nickel on the second steel core, the second layer of copper having a thickness of at most 24 μm, to produce a second coin having a second EMS defined by a second range of conductivity values that is distinct or non-overlapping with the first range of conductivity values, each of the first and second ranges comprising plus or minus 17% difference of International Annealed Copper Standard (IACS), and the second coin having a mass that is at most 0.01 grams more than the first coin. 2. The method of claim 1, wherein the first EMS is a known EMS of a circulation coin and the second EMS is a unique EMS not used in any circulation coin. 3. The method of claim 1, wherein the second EMS is a known EMS of a circulation coin and the first EMS is a unique EMS not used in any circulation coin. 4. The method of claim 2, wherein the thickness of the second layer of copper is 12-20 μm. 5. The method of claim 3, wherein the thickness of the first layer of copper is 12-20 μm. 6. The method of claim 1, further comprising electroplating a third layer of nickel over the first layer of copper on the first steel core and electroplating a fourth layer of nickel over the second layer of copper on the second steel core. 7. The method of claim 1, wherein the electroplating is galvanic electroplating. 8. A method of producing a unique circulation coin having a different electromagnetic signature (EMS) from a known circulation coin, the method comprising: selecting a steel core for the unique circulation coin, the steel core of the unique circulation coin having approximately identical mass and exterior dimensions as a steel core of the known circulation coin;electroplating a first layer of nickel on the steel core of the unique circulation coin; andelectroplating a layer of copper over the first layer of nickel on the steel core of the unique circulation coin, the layer of copper on the unique circulation coin having a thickness that is less than 20 μm different from a layer of copper on the known circulation coin, whereinthe less than 20 μm difference in thickness of the layers of copper provides the unique circulation coin an EMS comprising a range of conductivity values that is distinct or non-overlapping with the range of conductivity values of the known circulation coin, wherein the range of conductivity values of the unique circulation coin comprises plus or minus 17% difference of International Annealed Copper Standard (IACS), andthe less than 20 μm difference in thickness of the layers of copper provides the unique circulation coin with a mass that is at most 0.01 grams different from a mass of the known circulation coin. 9. The method of claim 8, wherein the thickness of the layer of copper of the unique circulation coin is 12-20 μm. 10. The method of claim 8, further comprising electroplating a second layer of nickel over the layer of copper on the unique circulation coin. 11. The method of claim 8, wherein the electroplating is galvanic electroplating.
