Problems solved by technology

[0003] Compared with copper alloys, nickel-plated steel coins have higher hardness, which limits the application of anti-counterfeiting technology. At present, the anti-counterfeiting technology used on nickel-clad steel coins is relatively simple. There is an urgent need to improve the anti-counterfeiting level of nickel-clad steel coins

Embodiment Construction

[0021] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] The invention provides an anti-counterfeit nickel-clad steel coin, see figure 2 The difference between it and the prior art is that invisible patterns, miniature characters and secret marks are set on the front and back of the coin at the same time, edge roll characters are set on the side of the coin, the invisible pattern is a double-sided invisible pattern, and the depth of the invisible pattern engraving is 0.01-0.09mm, the angle of the engraving knife is 15-40°; the miniature characters are letter...

Abstract

The invention relates to an anti-counterfeiting nickel-clad steel coin. Invisible patterns, miniature characters and secret marks are arranged on the front face and the back face of the coin at the same time, edge rolling characters are arranged on the edge of the coin, the invisible patterns are double-face invisible patterns, the engraving depth of the invisible patterns ranges from 0.01 mm to 0.09 mm, and the angle of an engraving knife ranges from 15 degrees to 40 degrees, wherein the miniature characters are letters, numbers or Chinese characters, the stroke width is smaller than or equalto 0.1 mm, and the character height is smaller than or equal to 0.35 mm; the secret mark is a pattern formed by combining letters, numbers or dot lines, the stroke width of the secret mark is smallerthan or equal to 0.1 mm, and the character height is smaller than or equal to 0.35 mm. Various anti-counterfeiting technologies are integrated on the same nickel-clad steel coin, so that the problemof single anti-counterfeiting technology in the prior art is solved, the public anti-counterfeiting level and the machine-readable anti-counterfeiting capability of the nickel-clad steel coin are improved, Meanwhile, the process is improved, so that processing and processing of various anti-counterfeiting technologies can be carried out on the nickel-clad steel coin made of hard materials.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeit coins, in particular to an anti-counterfeit nickel-clad steel coin and its manufacturing process, in particular to a nickel-clad steel coin combined with multiple anti-counterfeiting technologies and its manufacturing process. Background technique [0002] Invisible patterns, miniature characters, secret marks and edge rolling are all commonly used anti-counterfeiting methods for coins. Generally, 1 or 2 anti-counterfeiting technologies are used on coins. Yuan coins adopt two anti-counterfeiting technologies: invisible pattern and micro-pattern; there are fewer coins using three anti-counterfeiting technologies, and most of them are made of copper alloy. [0003] Compared with copper alloys, nickel-plated steel coins have higher hardness, which limits the application of anti-counterfeiting technology. At present, the anti-counterfeiting technology used on nickel-clad steel coins is relati...
