I'll add to this. Oldest Nickel I've found has been a 1930-S Buffalo Oldest Dime: 1957 Oldest Half: 1964 I still haven't found a silver quarter.
1917 wheat cent is the oldest but I've also found some buffaloes, war nickels and a couple of silver Washington quarters.
I found a 1936 S Cent last week in a roll I got from the bank when I got $5 worth. I have found older coins, but not this recently. I got a 1903 V Nickle in change 50 years ago. lol
Oldest penny-1940 Wheat Oldest nickel-1939 Oldest dime-1965 Oldest Quarter-1947 Never found halves or dollar coins in my change, ever.
