Mining Stocks & BondsOver the years, thousands of American companies have needed to raise money for their business. In order to do so, the founders of these companies issued securities. Generally they issued either an equity security (a stock) or a debt security (a bond).
Since each company is different, their certificates all differ greatly as well. From color, to paper type, to unique stamps or imaging, the stock or bond certificate of each company has its own collectible features.
