Abstract: A method to generate an optical signature of a coin is disclosed. A plurality of parameters are generated and recorded related to rotational positions around the circumference of a coin. The data from these parameters are combined to produce a searchable value.
Abstract: An apparatus to locate a coin comprises a rotary platform configured to hold the coin and a plurality of coin contacting mechanisms, coupled to the rotary platform.
Abstract: An apparatus for producing scattering signatures from a coin comprises a platform configured to hold the coin and an electromagnetic radiation source configured to produce a beam directed toward a portion of at least one surface of the coin. The electromagnetic radiation source is arranged to produce a far-field scattering signature upon interaction the at least one surface of the coin. A plurality of collection elements is configured to produce an electrical signal based upon collecting at least a portion of the far-field scattering signature.
