Last year of interest for me is 1964. EXCEPTION: State quarters but I'm working on getting rid of them.
I keep all 1982 and earlier pennies. Obviously all 64 and earlier quarters and dimes...any eisenhowers, but not susan Bs. And obviously any 69 and earlier half dollars!
Cents: 1958 and sometimes 1959-1975 Nickels: 1960? maybe 1969, but I always toss back 63 and 64 Dimes: 1975 Quarters: 1975. I like the Washington Quarters before the coin collecting program went into effect, so I will always prefer those Halfs: any. I like half dollars, but since I dont get them in regular circulation, I dont have a ton Dollars: I'll keep SBA's since I dont see a lot of them, but I really like the larger dollars, so effectively anything before 1978 These are all ballparks, because like most others, if I like what I see, I keep it.
I dont roll search small dollars and I dont really get them in change unless i go to a specific coin shop, so lol. Whenever I get dollars, its always the bills.
