Take a look at the very last picture. The soft hue is what got me I guess. And the wire rim. I know they began experimenting with satin finishes for proof coins, at least an article from the Smithsonian documents several d and strikes as early as 1958.
That is a very well preserved cent. The O of one and the AM of America shows strike weakness, which is common on business strikes. That shows the the press was running very fast when the coin was struck. And is also why the edge looks the way it does. Were did you find it?
Please don't mention this article or that article. Give us a link to the article! You did this same thing regarding the SQ "experimental finish" and you were so wrong it was pitiful. Chris
It's just a 57-D in good condition. There are still a number of 57, 58, and 59's in very good condition.
Unexpected 50+ 1957-D all bu red in a weird looking sealed thin plastic tube included in a auction with no description in the listing.
I can still see the cartwheel luster and much of the flow lines. To me, a satin finish will have a very muted appearance with no visible cartwheel luster.
Cents, especially late 50's D mint, come in a wide variety of surface finishes depending on the die state, how much die polishing and other work has been done, etc. Early die state coins can have a beautiful, almost-satin appearance. I suspect this may be the case with this coin.
