Abstract: The present invention relates to a multiple coin authentication system in which a plurality of coins are attached to a core. The core includes a plurality of openings therein. Coupling means are used for expeditiously coupling the coins to the core. For example, the coupling means can be a flexible gasket surrounding the coins which gasket snaps into a corresponding opening in the core. An authentication certificate is also attached to the core. The core is received in a cavity of a case. The cavity is formed between a top and bottom. The top and bottom are ultrasonically bonded together. The case is designed to include means for positively indicating sealing of the top to the bottom which means form a visible irreparable condition of the case indicative of tampering.
