Many people take coin collecting either as a hobby or as a kind of investment. But because money is a limiting factor, making decisions on where to spend it is always an important matter. So, consider the following factors when you need to make choices of coins.(22)First of all, try putting together a complete set of all the different classifications issued by the United States. Start with the coins in circulation. Then include obsolete coins like a half-cent, a three-cent piece or a 20-cent piece. Second, collecting by date is a fun and affordable way to obtain every date for a particular series.(23)For example, you could firstly collect a half dollar from every year they were made since 1900. Then, collecting every date and mark combination becomes a bit more challenging and expensive. Most series have a rare mark that can sometimes be prohibitively expensive. You don’t want to attempt to collect a set of Barber dimes unless you have a lot of money. Finally, the year. Many people try to buy every coin issued in the year of their birth.(24)If you’re under 50 years old, all you have to do is buy the coin sets issued by the government in the year of your birth. If you’re older than 50, you may have to search a little harder. But that’s half the fun of collecting coins, isn’t it?(25)The coins are not fragile as porcelain, nor do they require large spaces like antique furniture. So if you have the interest and some extra money, coin-collecting can be the right hobby for you.
