Collectible coins encompass various categories, including historical coinage, commemorative issues, and limited-edition releases. In the context of the United States, pre-1776 state coinage represents early colonial currency and reflects the diverse economic systems before independence. Notably, coins from 1659, such as the Pine Tree Shilling from Massachusetts, exemplify the unique designs and materials used during this period, making them sought-after items for collectors. These coins also provide insights into early American history and the evolution of currency in the region.
