@Santinidollar I'm confused the nickel just before my post has a date of 1926 and so does my commemorative half dollar. What should I have posted?
Agreed. Also, if a mistake is made it is easily corrected, no hassle. I can't even play when you show Franklin's, Mercuries or buffaloes as I don't own a single one. But it is just as much fun to see all yours.
Interesting P&G. That linear toning on the reverse of your 1963 is something that you would normally see on a 1960 (P mint) Franklin (and Washingtons and Roosevelts too). Much less commonly you'll see that sort of linear toning on a 1959. Your '63 is the first one of that date/mm that I've seen.
No one is really sure what causes it. It's definitely NOT storage, as it occurs on only one side of a coin, and occurs only at the Philly mint... notice how your Franklin is a P mint. The theory that makes the most sense to me is that it occurs during the rolling of the sheet of silver the planchets are stamped out of. Even for 1960 silver coins, which is by FAR the most common date for this occurrence, it's still not particularly common. Here's a 1959 which is, before your 1963, the only other date I've seen with this condition/toning pattern, and 1959's are significantly less likely than 1960's to exhibit this condition/toning pattern.
