1. A method of forming valid sets of gaming chips, the method comprising:
- emitting non-optical electromagnetic energy via at least one antenna;
receiving a first returning non-optical electromagnetic resonant response from a first resonant marker in response to the emitted non-optical electromagnetic energy;
deciding whether the first received resonant response is discernibly distinct from all respective resonant responses from respective ones of a number of resonant markers for which information indicative of the respective resonant responses has previously been stored in a computer-readable medium;
responsive to deciding that the first received resonant response is not discernibly distinct from at least one of the respective resonant responses from the respective ones of the number of resonant markers for which the information indicative of the respective resonant responses has previously been stored in the computer-readable medium, identifying the first resonant marker as a duplicate of at least one of the number of resonant markers for which the information indicative of the respective resonant responses has previously been stored in the computer-readable medium; and
deciding whether a second received resonant response from a second resonant marker is discernibly distinct from all respective resonant responses from the respective ones of the number of resonant markers for which the information indicative of the respective resonant responses has previously been stored in the computer-readable medium; and
responsive to deciding that the second received resonant response is discernibly distinct from all of the respective resonant responses from the respective ones of the number of resonant markers for which the information indicative of the respective resonant responses has previously been stored in the computer-readable medium, storing information indicative of the second received resonant response in the computer-readable medium.

Abstract
A system and method for a gaming chip identification system are disclosed. Briefly described, one embodiment comprises a plurality of gaming chips, each gaming chip operable to emit a respective unique electromagnetic signature in response to incident non-optical electromagnetic radiation, a computer-readable medium that stores information indicative of the electromagnetic signatures of at least a number of the plurality of gaming chips, and a processor-based system configured to verify that the electromagnetic signature from an interrogated gaming chip in an interrogation zone is a member of the plurality of gaming chips.
