Good job!
Finding a nickel over 50 years old is always a treat!
For me today $30 in nickels produced one keeper- a 1948-D. It goes in my third blue folder. My first one is complete, the 2nd needs only ten more, the 3rd needs 13 more and my 4th has 22 empty holes. Only 45 nickels away from four sets, woo hoo!
I did find a 1941 and a 1946 but returned them for other "high rollers" to find.
