Many people see coin collecting as a profitable way to invest money. This activity is very exciting. Collectors study the history of coins of various states. Many of them are treasure hunters.
The first collections of valuable coins began to appear in ancient Rome. At that time, only very we althy people could get involved in this occupation. After all, then only valuable specimens were collected. Coins were given as a gift for a birthday, wedding or other significant event. Expensive collections were inherited.

Coin collecting in Russia and the USSR
The first Russian coin was made in 1654. This is a silver ruble. Soon the minting of coins of smaller denominations began.
The fashion for collecting coins in our country arose during the reign of Peter the Great. The collection of the emperor himself is kept in the Kunstkamera. At that time, people tried to fill their collections with anyavailable ways. Copies of old coins were ordered at the mints. Sometimes entire collections were made in this way. The production of remakes was completely stopped only at the end of the 19th century. Many coins of that period were transferred to the Hermitage. He has over 1 million items in his collection.
In the USSR, buying coins was equated with speculation. But that didn't stop collectors. In the 60s of the XX century, the issue of commemorative coins began in the Soviet Union. This greatly increased interest in collecting among young people. The first commemorative coins were issued in honor of the twentieth anniversary of the Victory in the Great Patriotic War. Several thousand coins of improved minting were issued for collectors. Each of them was packed in a paper envelope. The largest collection of USSR coins was issued for the 1980 Moscow Olympics. Commemorative coins made of gold, silver and other valuable metals were also issued. The first commemorative coins of the Russian Federation were issued in 1999 in honor of the bicentenary of the birth of A. S. Pushkin. The development of the Internet has greatly simplified the search for valuable copies of coins. Now collectors do not need to spend a lot of time. Rare coins can be purchased at special online auctions.

Coins should be stored in a dark place whennormal room temperature. Direct sunlight can damage their surface. The method of storage depends on the properties of the metal from which they are made. Coins made of expensive metals are less demanding to care for. Today, most coins are minted from steel. They lose their original appearance after a couple of months.
Oxidation and patina
The causes of metal oxidation were found out only at the beginning of the 19th century. The metal combines with oxygen. As a result, oxides form on its surface. The development of chemistry made it possible to develop methods of protection. Copper and bronze coins develop a patina over time. This is a natural greenish coating on coins. Experts believe that it protects the coin from oxidation. Patina gives the coin additional beauty. Coins covered with patina are especially valued by numismatists.
How to store coins? The cost of storage should not exceed 30% of the price of the entire collection. Many banks provide similar services for high-value collection items.
