Art Work
Many people collect coins simply because they like the art work. Commemorative coins can have detailed pictures on both the front and back.
History
Older coins often have stories behind them. Holding a coin from 1835 and wondering who held it before can be inspiring for a coin collector.
Investment
Most coins increase in value as they get older. In this way, collecting coins can be a valuable investment.
Travel
Some coin collectors enjoy collecting coins that they acquired while traveling. Such a collection can remind the collector of trips to foreign countries.
Gold Coins
Some coin collectors prefer to make their gold investment in coins rather than bullion because of the small size of the coins. In addition, gold coins are often easier to sell than gold bars if a collector needs to cash in an investment quickly.
