How valuable is flint?

Flint is a valuable material primarily for its historical significance and practical uses. In ancient times, it was crucial for tool-making and fire-starting due to its ability to create sharp edges when struck. Today, while less critical than in the past, flint is still sought after by collectors and used in certain industrial applications, such as in the production of high-quality glass and ceramics. Its cultural and archaeological importance also adds to its value.
