Coin collecting is a truly fun hobby to get into, especially as you become more and more familiar with different coin types, their respective age, and how limited the production is. However, not all coins are available to the public. The rarest and most valuable ones are often just sold in high-end auctions or kept in museums (finding ones for sale is reason enough to think they might be fakes). Hereunder are some of the most collectible ones that should make the devout numismatist’s mouth water.
