Abstract

A device for preventing oxidation of gold / silver coins comprises a glass ware, a plastic box and active carbon, wherein the glass ware is subjected to grinding treatment; the plastic box is arranged in the glass ware and comprises a box body and a box cover; the top of the box body is provided with an opening; the box cover covers on the top of the box body and the opening is covered tightly; the box cover is provided with a plurality of through holes; and the active carbon is placed into the box body via the opening. The device has good effect, is simple and convenient, has strong operability and solves a problem that the gold / silver coins are easily oxidized from the source.

Description

technical field [0001] The invention relates to a device and method for preventing oxidation of gold and silver coins, and is especially suitable for collectors of gold and silver coins. Background technique [0002] After a period of time, the gold and silver coins collected by many investors and collectors, even if they are sealed by the original factory, due to improper storage, rust spots will appear on the gold and silver coins, and the quality will be downgraded. The rating drops by a certain value. [0003] The oxidation characteristics of gold coins are mainly manifested as reddish-brown rust spots, the large red rust spots have a diameter of 1-2 mm, and the small ones are like fly poop star cloth. Usually, the rust spots on the smooth surface of gold coins are relatively large, while the rust spots on concave and convex parts such as patterns and edges are small, mostly in the form of tiny dots, and some are even difficult to detect with the naked eye. [0004] Th...
