Consider collecting colonial coins—four C’s in a row. This is an ideal way to introduce you to C4, the Colonial Coin Collectors Club. Founded in 1993 by Mike Hodder and other enthusiasts, the club has several hundred members today. Check the website and join. You will have a great experience!
The field of colonial coins also includes some issues after 1776 but before the Philadelphia Mint opened in 1792. These later issues include the copper coins of Massachusetts, Connecticut, Vermont, New Jersey, and New York, and many varieties of coins featuring George Washington. While there are many rarities, by and large, the formation of a set of representative issues is very affordable. In grades of VF and EF, considered to be high-level for early issues, many are priced only in the hundreds of dollars.
If this comment piques your interest, a good place to start is with the Guide Book of United States Coins. The narrative in the very front tells of early issues, after which there are many illustrated pages of listings.
Nearly all colonial coins have interesting histories. Forming a collection and also joining C4 can be your passport to a lot of enjoyment.
