I read somewhere maybe wrongly that the 1946-S had an erroneous MM style type error. I came across some recently and the MM look different. Question are the styles different, and if so is this an error? Or am I seeing things LOL
Some info here on this link, it says two different styles for 1946. .http://www.lincolncentresource.com/San_Fransisco_Mintmark_Styles.html
Two at the top are serif and the bottom is a sans serif mintmark. There is also a ball serif mintmark. This is the only pic I have saved at the moment, it's my rpm#25 , the only rpm for the ball serif style. 1946 S rpm 25 b by stoneman227, on Flickr There are two big ones for 46-S , a inverted Balls serif style and a S/D with the S being a serif style
The years that I know in the Lincoln cent series that have multiple styles of S mintmarks are 1928 1941 1944 1945 1946 1947 1952 , maybe this year 1979 1981 Here is a page that shows the styles of S mintmarks through the years. http://www.lincolncentforum.com/san-francisco-mintmark-styles/ Jason tried to show lightly and deeply punched examples of each style but a deeply punched example of the Sans Serif from 46 is missing so I will post a pick of one I have 1946-S sans serif by stoneman227, on Flickr Since this post was originally about 1946 here is an example of the third MM style from this year, a Serif style. This is from a later die state coin, a RPM-022. This is one of the rpm's that gets stronger as the die ages. 1946-S 022 by stoneman227, on Flickr
