Abstract: An improved coin holder for the storage, display and protection of graded coins and other valuables is disclosed. Various tamper-resistant and tamper-evidencing features of the coin holder discourage and prevent fraudulent attempts to obtain access to replace graded coins with those of lesser quality, or tamper with coin grading certificates sealed with the coin in an inner element. Additional features discourage and make difficult the wholesale counterfeiting of the coin holder itself. The coin holder may be partially disassembled to obtain direct, unobstructed access to the coin contained therein, while maintaining the integrity of the grading certificate retained in the inner element along with the coin. The device introduces greater security and certainty into the process of marketing graded and increasingly valuable numismatic items.
