Investment coins are specially minted coins that are primarily purchased for their potential to appreciate in value over time. Unlike regular currency, these coins often contain precious metals like gold, silver, or platinum, which can increase their worth based on market demand and metal prices. Collectors and investors often seek these coins for both their aesthetic appeal and their investment potential. Many investment coins are produced by government mints and come with a guarantee of weight and purity. Popular examples include the American Eagle, Canadian Maple Leaf, and South African Krugerrand. Investors typically buy these coins as a way to diversify their portfolios and hedge against inflation.
