An unknown item of currency is compared to at least one known item of currency by evaluating the spectral response of the unknown item of currency. A spectral response is obtained from the unknown item of currency, and the spectral response of the unknown item of currency is separated into a first component and a second component. At least one component of the spectral response of the unknown item of currency is compared to at least one component of the spectral response of at least one known item of currency having a specific denomination. A determination is made as to whether the unknown item on currency is a member of the class of the at least one known item of currency.
