Collectible coins encompass various types, including official currency, tokens, and medallic items. U.S. collectible coins, such as the 1 One Dollar denomination, may include commemorative issues or unique designs celebrating historical events. Tokens often serve specific purposes, like promoting a business or commemorating an event, while fantasy coinage refers to non-official pieces made purely for collector interest. In 2023, the market remains vibrant, with an emphasis on rarity, historical significance, and unique design elements influencing value.
