Dave is correct above. No, it's not normal but does happen often when grease or other compacted debris fills the area and a good strike is not possible. A bit of a premium possibly but not much.
I'm sorry but no. A coin would have to be worth on average $150.00 or more to make it worth the effort and expense. This is only a 25 cent coin at the best, providing you could find someone to buy it. It is neat coin to have and save though.
