1. An apparatus for producing scattering signatures from a coin, the apparatus comprising:
- a platform configured to hold the coin;
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 further configured to produce a scattering signature upon interaction with the at least one surface of the coin; and
a plurality of collection elements configured to produce an electrical signal based upon collecting at least a portion of the scattering signature.

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.
