Abstract
A coin selector is provided which is adapted to electronically sample coins and compare the sampling data to stored data for genuine coins. The stored data can be preset or can be acquired and stored in memory by using a key coin. Data stored determines if a key coin is authentic and if it is, places the selector processor in a condition to accept and store new or modified data for determining the authenticity of other coins.
