Claim Text:
1. An apparatus for storing a digital coin, comprising: a non-transitory computer readable medium that contains a digital coin; a tamper proof housing that encloses the non-transitory computer readable medium and is made of such a material so that when the housing is opened to obtain the non-transitory computer readable medium and read the digital coin the tamper proof housing cannot be returned to its virgin condition; the digital coin containing visible markings of the digital coin's nominal value and the identity of its mint; and wherein the digital coin is marked with a dynamic identification code that changes at given time intervals based on cryptographic protocols, allowing the digital coin holder to contact the mint that minted the digital coin to verify its authenticity and viability; track digital coin history for the digital coin wherein the dynamic identification code of value-indicating bits are randomly determined by the mint that minted the digital coin; wherein the digital coin holder redeems the digital coin by presenting the dynamic identification code of the value-indicating bits: few of the digital coin's representative bits within the coin are masked by the payer unbeknownst to a payee (the digital coin still appears random) such that the mint upon inspecting the digital coin submitted for redemption will authenticate the digital coin on account of the identity using the digital coin's bits, including the masked bits which the mint detects; wherein the masked bits are editing binary code for history tracking; and wherein the payee trades the digital coin to a third trader, and similarly masks a few bits, and so on, trader to next trader; the identities of the various masked bits will indicate to the mint who owned the digital coin.
