This dime just grabbed my attention and I’m wondering if it’s something more than just damage. The bust / center looks good and strong but the remainder is hardly there. I apologize for the lousy photos but these were the best I could do Thanks
When a coin die begins to wear out, it has a tendency to make the metal flow, thus leaving those lines at the outer edge. A sure sign of a worn die. https://www.error-ref.com/radial-flow-lines/
