Coin collectors from every corner of the globe have, at one time or another, come across a certain coin and wonder whether what they have in their possession is something of enormous value or just a piece of junk. It is important that, as a coin collector, you learn about the key factors that determine, or at least influence, coins value in order to be guided in your quest to find treasures of yore. There's more to a coin than its face value, and of course, just because a coin does not carry significant monetary value does not mean you should not covet it to form part of your precious coin collection.

There are basically five factors that determine or influence the value of a particular coin. These primary factors are the coin's rarity or scarcity these days, its bullion value, the demand for it among collectors today, its grade or condition, and its quality. Keep reading to find more about each of these primary factors and be enlightened about coin value estimation.

Obviously, coins value is greatly factored out by its rarity or scarcity – this is the cause of great joy and pride in a coin collector. The general rule is, the more rare a coin, the higher its value. There are some coin collectors that continue to be misled by what rarity or scarcity means. The age of a coin or when it was minted and distributed have nothing to do with its rarity or scarcity. If there are only a few, maybe even just one or two, coins around like the one you have in your hands (today, not during the period of its circulation), then your coin is no doubt rare or scarce and definitely priceless.

The bullion value of a coin is determined by the value of the precious metal it contains. In general, gold coins, silver coins, or platinum coins do not sell at a price below their melt value. A coin expert can help you with this.
If many coin collectors want the coin in your possession, then you can count on your coin to have high value. Coins value is influenced greatly by the demand or clamor for such coins.

Rarity or scarcity and demand are independent factors. This means that, while a coin may be rare, not many coin collectors are sure to prefer it over other coins that are relatively plentiful. For example, more coin collectors look out for early twentieth-century mercury dimes than other dimes from other periods. A dime from the eighteenth century, while rarer, thus has less demand. The total value of a coin will depend on all the factors taken into consideration, not just one or two of them; rarity or scarcity, demand, and the rest of the factors will be weighed together to get or estimate one coins value. However, some coin collectors have observed that coins in greater demand, while not so rare, value more than their rare counterparts.

Some coin collector have this notion that if a coin from centuries past were to be found, it has to be in bad shape in order to spark authenticity and command greater value.
