This half dollar has a weird texture to it... It's not like most of the rest... is it anything? It's hard to describe... I think the best word would be rustic... It's not shiny like the others adn doesn't feel the same as others I have seen...
it doesn't really feel rough... it feels like a normal half dollar just ... dull... maybe even a bit lighter than the others.. hard to tell without a scale though
Yes, it's called circulation. I've seen thousands of them when I used to search $500 boxes regularly. Chris
