Abstract
A method and apparatus for discriminating among a plurality of coin denominations includes sensing the characteristics of a test coin with a test coin sensor and comparing the characteristics of the test coin with characteristics of a plurality of coin denominations thereby producing comparison signals. If the comparing results in a match between the characteristics of the test coin and characteristics of one of the coin denominations, then the test coin is declared to be the matched coin denomination. If the comparing results in matches between the characteristics of the test coin and characteristics of more than one of the coin denominations, then the matches are compared to each other to determine which of the matches represents a valid match. The test coin is declared to be the coin denomination which corresponds to the valid match.
