I've always collected coins. Love metal detecting. Just a few months ago I realized that many coins have errors but unless it's a real obvious error they are hard to see. I bought myself a microscope and started taking a closer look. My first find was a 1942 d/horz d nickel (pic below). Since then all I've found were coins with
Machine Doubling.... Until today.
I think...
Are any of the coins below doubled... Or have a rpm.
Coins pictured below not in any order;
1996 d half Dollar
2000 p Sacagawea
1964 p nickel
1972 d half Dollar
1997 p nickel
1984 p nickel
1981 p nickel
I'm just trying to get a feel for what doubling actually looks like. And rpms. Thanks
