Kinds of Coin Collections
There are many different types of collections. The most common types or themes of collections are the coins from different countries and time periods. Usually, coin collectors who collect coins from different countries strive to acquire current or past coins from as many countries as possible. This would most likely be a never ending collection since some countries change their currencies often. Year collections focus more on a specific coin and denomination like the Lincoln penny, which was minted in 1909 up to the present.
Error collections are more focused on coins with mistakes on them. These mistakes may be very obvious or not at all. The older coins usually have mistakes since coins were minted by hand before the 19th century. Common errors are double dies, overdates, double strikes, repunched mint marks, off metal coins, displace coins, clipped coins and mules. Mules are very interesting coins because each side of the coin has a different denomination. Collectors desire the coins with errors because they are very unusual and one can seldom encounter them nowadays since minting is now fully automated.
