Know a coin from a medal
They may look similar but coins have a face value and past or present purchasing power, whereas medals are coinage without a face value.
Store your coins with care
From albums and cases to boxes and suitcases, there are many different ways to store coins. But whichever method you chose, guarantee your coins keep their value by storing your collection in an appropriate manner. Coins should also be protected against moisture and polluted air, while Proof quality coins should be kept in their protective capsules at all times.
Care for your coin
To avoid finger prints and sweat damage never touch high quality coins with your bare hands. Use soft gloves or special coin tweezers instead and always use an ultrasonic cleaning device in place of potentially damaging silver cleaning products.
Treat coins like living things
Even after you have done everything to guarantee that your coins maintain their shine, pieces made of silver and copper, for example, will change over time. For experts this is a sign of the metal’s authenticity, so ordinary tarnishing over the years should not alarm you and cause you to overclean your coins.
Do your homework before starting your collection
Coins last for thousands of years and there are literally thousands of different themes and subjects for collectors to choose from. Before starting your collection get an overview of what is available by researching on the Internet or by reading specialist literature. Whether you collect antique, contemporary or gold coins you can search by issuing country, motif or face value.
Check for authenticity
If possible always buy valuable coins in specialist shops or banks and always make sure you buy them from a trustworthy vendor.
Know obverse from reverse
Numismatically speaking the front of a coin is known as the obverse (heads), the other side as the reverse (tails).
Be careful with coin condition
A coin's condition is absolutely vital to its value. The same coin can vary in value from anything from 10 to 200 euro depending on its condition alone.
