Definizione

• Mintage.  The number of pieces produced of a single kind or variety (from the same dies, or from the dies of a single hub); the quantity struck usually within a year’s time or bearing the same year’s date. Mintage is reported by the officials of the minting agency and numismatists are somewhat at the mercy of these officials to obtain this desired information.
  Mintage, coinage produced, is a quantity struck. This figure must be analyzed for any meaningful data because of the opportunity for any coinage to be destroyed or melted. Quantity issued is more meaningful; quantity preserved is even more meaningful. These figures are important to ascertain the supply of the item in existence, thus is a factor of value (of importance to collectors).
  The number struck must be modified as to the number in existence at any time. A far more meaningful figure is that of survival ratio – the number struck divided by the number in current existence.
