Abstract
Coins may be validated and denominated by comparing varying signals from coin sensors and checking whether a predetermined relationship between them is maintained, for example, as the coin moves past die sensors. In some implementations, each varying signal may represent the varying effect on a sensor as the coin moves relate to the sensor.
