I am not a coin collector but after going through my parent house and sorting though stuff to keep, sell or donate, we got to a box of coins dad had been buying each year since 1965. Full untouched mint sets, single old pennies in plastic wrapping and such. I got some and my 2 siblings took some. They aren't worth anything to me, that I'm aware of but I'm open to any insight on a reason to keep em or a value if I were to sell them and where to take them to sell.
