Ok I know Philadelphia did not make 5 cent pieces in 68, 69, 70. Also did not put the mint mark on til I think 1981. Also I know they ordered
no mint mark for all coins at that time to discourage collectors because of the coin shortage. Now in 1971 Philadelphia started making nickels but with
no mint mark and put the P mint on nickels in 81. My question is..... What year did the
no mint mark end, would a 1970 nickel with
no mint mark be a D coin, and would a 1981 nickel with
no mint mark be a error?Sorry if this is the wrong topic. I cant find general question forum. Thank you for your time.
