What not to do when collecting coins


If you’re thinking about collecting coins, as a hobby or an investment, (A.K.A. numismatics), here are a few things you’ll want to make sure you DON’T do:


  1. Buy without doing serious research

    Just like other types of investments, the coin market can be volatile. Not every coin is a good investment. It’s easy for new-comers to get taken, unless they do their research and due diligence about the market and their potential coin purchase. However, for those with the right attitude and education, collecting rare coins can be a fun hobby and an excellent hedge against inflation.

  2. Purchasing from a vendor who hasn’t been thoroughly vetted

    You wouldn’t buy an expensive diamond ring from a street vendor, so why buy a rare coin from someone you don’t know and trust? Make sure you work with a reputable, qualified coin dealer to ensure that you’re making a legitimate purchase.


  1. Forgetting to check the coin’s authenticity

    While a coin may look like the real thing online or even in person, if you’re not absolutely sure of its authenticity, have the coin evaluated by a third-party grader. A grader is neither a buyer nor a seller and has no interest in the coin’s market value. You can find a professional grader through the Professional Coin Grading Service (PCGS). Some coins come with a PCGS certificate and will be hermetically sealed into a plastic holder with interior labels.

  2. Not understanding what makes a coin valuable

    While most coins are not worth more than ther face value, some are worth much more. Here are a few things to look for when determining your coin’s value:

    • Demand – Like other investments, higher demand increases the value. So those coins that are in high demand will command a higher price.
    • Grade – This is the condition of the coin. Coins are graded on a scale of 1 to 70, with higher quality coins getting grades close to 70. Coins are graded on the strike, visual appeal, colouration, lustre, and any damage, including dents, scratches, corrosion and carbon spotting.
    • Strike – This term describes the process of stamping a coin with a design. A well-struck coin will have a design that is without errors or defects.
    • Content of the coin – Coins made of silver and gold will be worth more than those made of copper, bronze and steel.
    • Age – Sometimes, the older the coin the more valuable it is, though this is not always the case.
    • Design – Coins are often collected for their aesthetic value, or how beautiful they are.
    • Rarity – This may be the most important factor in a coin’s value. Rare coins will be more valuable than coins that are easy to come by.


  1. Keeping your coins at home

    Coins can deteriorate if exposed to cigarette smoke, rubber, paint, textiles such as wool and felt, and too much humidity. Keep your coins pristine by storing them in airtight plastic holders, such as the encapsulation slabs of third-party grading services. Then, put them in a secure place like a bank safe deposit box for safe keeping. Unprotected coins are easy prey for a thief who breaks into your home.

  2. Not insuring your investment

    Like your other valuables, coins may be insured, so that they can be replaced or repaired if damaged, lost, or stolen. Look for an insurance policy that will provide accidental damage, worldwide coverage with no deductible. Some policies will also provide a limit of automatic coverage for newly acquired coins.
