Collectible coins encompass a wide range of numismatic items, including currency, tokens, and medals. In the United States, collectible coins can include historic pieces such as the 1856 Trade Tokens, which were private and often used for commerce in the absence of standard currency. Rulau refers to a cataloging system for these types of tokens, particularly focusing on their recognition and valuation. Trade tokens were typically issued by businesses for use in exchange for goods and services, and they hold significant interest among collectors and historians alike due to their unique designs and local significance.
