摘要

The coin has one or more codes for identifying the coin, where the coin is encoded with feature consisting of elements with a specific layer shaped color indication. The elements are made of a plastic material in a particulate form with a colored layer structure specific to a particular currency, where the colored layer structure of the element is maintained so that the element remains traceable. An independent claim is also included for a method for making a trade currency.
