If you have a gold coin, it deserves to be protected. It deserves to be kept in a safe place where it will not be harmed. There are not that many gold coins in the world anymore. The whole idea of currency has shifted with the invention of credit cards and the computer age. In many parts of the world, coins have been replaced by paper bills. If these bills are used at all - instead of credit cards - they are certainly not made with any gold. Money has become much more theoretical; the paper that it is printed on has very little value on its own.The first thing that you need to do to protect your gold coin is to make sure that it is always kept out of the reach of children. You will find that children are very curious. They like to look at things that they have never seen before. They like to play with them. You need to make sure that the coin is up high at all times so that this cannot happen. Even if the children do not damage the coin, they could lose it.You may also want to keep the coin in a glass case. If this is airtight, so much the better. This will protect it from the effects of oxygen and moisture, two things that can be very harmful to metal. Even though gold does not corrode in the same way that iron does, you still want to make sure that it is exposed to as little of these things as possible. A glass case is perfect since you can still look at the coin even without taking it out.What you might want to do is to buy a glass case with a lock on it. Then, you can store the coin anywhere that you want. You will always know that it is safe from the elements because it is enclosed. You will know that it is safe from children because it is locked up. This will create the ideal situation so that the gold coin will always be safe while it is in your home.
