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.
