Like nearly every other commodity, the value of a coin is determined by supply and demand.
The number of coins minted in a given year at a specific mint is the best indicator of supply, and production data is readily available. However, when the quality control process at a mint breaks down and defective coins get into circulation, this can create an explosive market of its own due to the very small supply of these unique pieces.
On the demand side, coin buyers want coins that are in good shape. When grading a coin’s condition, Numismax follows the guidelines of the most reputable grading organizations.
The historical context of the coin also can affect demand and its price. For example, the alloys used to make many U.S. coins during World War II were visibly different from those that were used in the preceding and subsequent years. This type of oddity typically drives demand by casual coin collectors and those who collect for historical significance.
