Here are some examples of what they might have used for trade:
* Agricultural produce: Corn, beans, squash, pumpkins, and other crops grown by the Lumbee were important trade items.
* Animal products: Deer, bear, rabbit, and other game hunted by the Lumbee were used for food and trade.
* Crafts: Baskets, pottery, woven textiles, and tools crafted by Lumbee artisans were also used for trade.
* Labor: They might have traded their labor for services or goods, such as helping build houses or clearing fields.
It's important to remember that the Lumbee were (and are) a diverse group with varying practices. The specifics of their economic system would have varied depending on location and time period.
Note: The Lumbee people were not officially recognized as a tribe until the 1950s. This meant they weren't subject to federal policies like the Indian Removal Act, which often resulted in the introduction of money and trade in other Native American communities.
