Numismatics is defined as "the study or collecting of coins, medals, paper money". It is derived from the Greek word "nomisma", i.e. coin. The science of coins and money as well as their history.

However, since the late 1980s, when coin collectors around the world use the word 'numismatics', they would generally mean the study of coins in particular, although it extends to wider definition to the study and collecting of all money related items such as banknotes, tokens, medals, bullion rounds

Now, the next word is "Numismatist" which is actually defined as a scholar who studies the science of Numismatics.

However, in today's context, the term numismatist has been used to mean generally anybody who is really serious about their coin collecting. The who are more advance in this hobby will include one grades, catalogs, or sells coins for a living. In another word - a coin collector

The community of coin collectors has grown tremendously especially over the 15 years. It has also evolved to more than just the passion of collecting coins and studying their history. Collectors are appreciating the fact the some coins do appreciate in value over a period of time and this can be an investment. To venture into the area of investment, you will need to do some research, buy some books and magazines and joining online forum to know what is happening in the numismatic area. Older coins tend to have a better premium, depending on condition and mintage. However, modern coins can also be a good investment. For example, a 2001-D American Buffalo Silver Dollar is retailing above $130 to over $$300, depending on condition, whether it is a raw coin or graded and if graded, buy which 3rd party. A slabbed 2001-D American Buffalo Silver Dollar graded MS70 by PCGS can fetch above $1000. The original release price was $32 for a Uncirculated and $37 for a proof in 2001.
