Collectible coins can include various types such as currency, medals, and commemorative issues. The United States dollar coins, particularly the 1 Dollar pieces, are popular among collectors, with iconic designs commemorating significant figures or events. Disney medals, especially those produced in 1987, often hold nostalgic value and are sought after by both Disney fans and numismatists. The designation "N/A" may indicate that a coin or medal has not been graded or lacks specific information that could influence its market value.
