Abstract: An aureate coin, coin blank, medallion, medallion blank, token or token blank has a coin-shaped core with opposed faces and a peripheral side edge and of mintable metallic material. An electroplated coating of copper and tin completely encases the core and provides a golden appearance. The electroplated coating contains from about 8 to about 16% tin by weight and has a thickness of from about 10 to about 150 .mu.m.

Abstract: A blank suitable for minting to form a coin or similarly disc-shaped article has an appropriately disc-shaped steel core completely encased by a copper coating electroplated thereof. The blank is produced by electroplating a copper coating onto an appropriately disc-shaped steel core such that the copper coating completely encases the steel core.

Abstract: A process for the production of coin blanks suitable for minting into coins, includes providing metal coin core pieces of disc-like shape each having opposed faces from about 14 mm to about 40 mm in diameter and a face to face thickness of from about 0.5 mm to about 2.6 mm. A charge of core pieces is loaded into a non-conducting perforated container with a diameter of from about 15 cm to about 50 cm, the number of core pieces in the container being such that the core pieces occupy from about 1/4 to 1/2 of the container volume. The container is placed in an electroplating bath, and a metallic cladding is plated on the core pieces, while moving the container angularly about a horizontal axis, at a voltage of from about 6 volts to about 18 volts and a current density of from about 470 A/m.sup.2 to about 1400 A/m.sup.2 based on the exposed area of the charge, until a plating thickness of from about 0.03 mm to about 0.

Abstract: A process for the production of coin blanks suitable for minting into coins includes providing metallic core pieces, each core piece having opposed, substantially planar faces and a common side edge. The core pieces are loaded into a perforated container which is placed in an electroplating bath. A metallic cladding is placed on the core pieces, while moving the container angularly about a horizontal axis, until the metallic cladding has a thickness of at least about 0.05 mm on each face of each core piece and a thickness of at least 2 to 4 times the face thickness on the side edge of each core.

Abstract: A two-component blank suitable for minting into a coin is described. The blank consists of a low-carbon steel core completely encased in nickel. The blank has magnetic properties sufficiently similar to a solid nickel coin of the same size that the minted blank is accepted by magnetic property testing coin discriminating devices which accept pure nickel coins.
