The 1964's I'm mentioning are Canadians, but as far as US cents, yes, I do notice quite a lot of early Memorials that look like they're right out of a BU roll. So much so that my #2 Lincoln Cent Whitman folders have pretty much all shiny, new-looking Memorials. I'm keeping all pre-1982 coppers in very large casino cups (already have one full) and a quick look thru a handful shows some shiny ones. Wonder where they sit for so many years to stay new-looking.
