The most ordinary type of coin collector is the casual collector. Casual collectors are both kids and adults. They collect random coins because they like the fun of it. The casual coin collector does not spend as much money on buying and preserving coins as a more advanced coin collector. Casual coin collectors usually have interest in coins with a special meaning to them, like for instance a coin minted in their year of their birth. Casual collectors often get hold of more interesting pieces as gifts from friends or family members. The gift of a rare coin has transformed many casual collectors to curious collectors instead.

Curious coin collecting

When a collector goes further than just circulation finds and getting gifts. He develops more of an interest in coins and becomes more a curious collector. The curious collector will buy some inexpensive coins, maybe look around coin shops or look at coins on eBay or other related internet sites. That way a survey of potentially interesting areas of coin collecting is made, and as the curious coin collector interacts with more seasoned collectors, he is bit by bit learning the trade of buying or selling coins. Like for instance studying coin books before making any serious decisions about buying expensive coins. At a point most curious collectors learn enough to become an advanced coin collector.

Advanced coin collecting

Every advanced coin collector is a unique coin collector. Some are dedicated generalists looking for a few examples of all kinds of coins. If they do have enough resources, this can result in an astounding collection, as that of King Farouk of Egypt, who collected everything he could get his hands on.

Many coin collectors are completists who want an example of everything within a certain set. For instance Louis Eliasberg was the only coin collector thus far to assemble a complete set of known coins of the United States. Other coin collectors focus on coins of a certain nation or historic period. And some collect coins from various nations or settle on error coins or exonumia like tokens and medals. As you can see, it can vary a lot.

At the highest levels of coin collecting, it is a highly competitive sport. It can lead to astronomical prices as enthusiastic collectors struggle for the very best examples of each date and mint mark combination.

Historical coin collecting

Coin collectors of ancient and medieval coins are more interested in historical significance than other coin collectors. The coins of Byzantine, Roman, Indian, Greek, Celtic, Merovingian, Parthian, Ostrogothic and ancient Israelite origin are among the most popular ancient coins collected. Specialties tend to vary a lot, but the common approach is collecting coins minted during a particular emperor's time in power. A completist would for example strive for a representative coin from each emperor.

National coin collecting

Usually coin collectors of national coins specialize in the coins of their own country. A common way to collect national coins includes collecting one of every date and mint mark for a particular series. This is termed collecting by type. For instance a date set in Britain may include one Queen Victoria large penny for each year, 1837-1901. In another example a U.S. type set might include an example of each variety of each denomination produced. Most coin collectors of national coins create unique combinations of date, mint mark and type sets.

Error coin collecting

Collecting error coins is a modern development made doable through the automation of coin manufacturing processes. Coin collectors of ancient and medieval coins; accept coins with errors because manual coin manufacturing processes lend unique features to each coin struck.

Examples of coin errors could be repunched mint marks, doubled dies, double strikes, overdates, off metal coins, clipped coins, displaced or off center coins, and different denominations on two sides of one coin.

World coin collecting

World coins are collections of relatively recent modern coins from nations around the world. Geography is often the engine for this type of collector; he can travel around the world through his coin collection. Many collect by subject, for instance collecting coins from around the world featuring animals.

World coins are usually inexpensive and may be a good starting point for children. Most children find foreign coins by looking under change-to-cash machines, where customers throw away assorted coins found in their penny jars. It is possible to find coins from all over the world, ranging from Canada, to South Africa, to Korea.
