In most cases, national coin collectors are only interested in collecting their own country’s coins, from past to present. It is a very usual practice for national coin collectors to get a coin from each date and mint marks for each coin series. This will lead them to have a very unique variation of series, date and mint marks of coins in their country.
The common characteristics of coin errors include the following:
- dies that are doubled
- mint marks that are mis-punched or re-punched
- over-dated
- double strikes
- coins that are “off” metal
- coins that are displaced or off center
- coins that are clipped
- one coin with different nominations both two sides
Collecting world coins is about gathering current coins from all the countries of the world. This usually applies for people who travels very often throughout the world, or have friends who do that.

Collectors of historic coins find value in mints that are from medieval or ancient times. Some of the most popular historic coins include the following :
- Byzantine
- Celtic
- Greek

There are other ancient coin specialties but it really depends on the preferences of the collectors. The popular way is to collect the coins that were minted during the reign of a certain emperor or king.
