Rare Coins

If you have been collecting coins for any length of time, chances are you have come across a coin or two that made you stop and wonder if you were in possession of a rare and valuable coin. If you are a novice coin collector chances are at some time in the future you will have that experience.

As a numismatist, it is important to know how to determine whether or not a coin is rare and, if it is, knowing which resources to use to determine the coin's value.

How To Identify a Rare Coin

There are several factors are used to determine if a coin is considered rare. Each coin is rated for its rarity based on the coin's date and mintmark. To determine the rarity of a coin, the total number of coins in the original mintage and the estimated number of coins from that mintage that have survived through the years are taken into consideration. In other words, a coin's rarity is based on the number of that specific coin that are still in existence.

Some coins are considered "condition rarities." This means the specific type of coin is commonly found at lower grades but is considered to be a very rare when it is a higher grade. Other types of rare coins include circulation strikes and proofs.

Rare Coin Values

The value of a rare coin is determined by the following criteria:

  • Rarity or scarcity
  • Condition or grade
  • Demand
  • Quality
  • Bullion value

Rarity or Scarcity

The value of a coin depends greatly on its scarcity or rarity. Generally, the rarer the coin the higher the value.

Condition or Grade

The condition or grade of a coin has a great influence on a coin's value. My Coin Collecting provides an explanation of the coin grading system, its standards and a coin grading chart. The Professional Coin Grading Service, known as PCGS, is considered by many to be the industry standard for coin and rare coin grading services. Their website also includes:

  • Updates in real time
  • A coin price guide
  • Population reports
  • Listings of realized auction prices
  • Condition census
  • Online photograde services


The value of rare coins, just as other coins, antiques and collectibles, depends greatly on the law of supply and demand. The value is greatly affected by the number of collectors that want the coin and the number of coins that are available.


The quality of a rare coin refers to the aesthetic beauty of the piece. There are certain coins that are in higher demand because their designs are considered by collectors to be more desirable than others. Two coins can be graded the same, but one may have a higher visual appeal than the other.

Bullion Value

The value of some gold, silver and platinum coins is based on their bullion value.
