摘要：
A composite coin, coin black, medal or token structure provides an inner stack, an outer ring surrounding the inner stack, and a separator, an authentication method and method of manufacture for the same. The inner stack comprises one or more inserts stacked on top of each other. The separator is disposed between the outer ring and the inner stack separating the outer ring from the inner stack and separating the plurality of inserts from each other.
技术问题语段：
The patent text describes a new composite structure for coins that includes an inner stack of inserts, an outer ring, and a separator. The technical problem addressed by this patent is to provide a new way of creating composite coins that offer improved security features and ease of identification in coin readers. Previous methods have involved locking the inner and outer rings together or using ridges or grooves to join the two components. The new approach involves a separator that separates the outer ring from the inner stack and the plurality of inserts from each other.
技术功效语段：
The present patent is about a new composite structure for coins that includes an inner stack of inserts, an outer ring, and a separator. The inner stack is made up of multiple inserts stacked on top of each other, and the outer ring is annularly surrounding the inner stack. The separator is placed between the outer ring and the inner stack to separate them and prevent them from coming into direct contact with each other. This new structure provides a unique way to create coins with different materials in the inner and outer rings, which can be easily identified and validated by coin readers.
