What You Need to Know

Coin values are primarily based on rarity (a reflection of the number originally minted), the condition of the piece and the demand for the item. “Condition” can be a little subjective but fortunately there are very detailed grading standards used by reputable organizations like the American Numismatic Association that help in this process.

Still, in spite of those standards, there often is some variability in estimating the value of a rare coin from appraiser to appraiser You can be confident that Numismax will give you the best possible offer.

Why can we make that assurance? Our expertise in grading and evaluating coins is second to none. Numismax’s buyers are in tune with the rapidly changing numismatic markets. We pay more because we know more!

Coin Value

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.

Not only do we buy coins, we sell them too.
