grospoisson Pillar of the Community United States 984 Posts	Posted 02/08/2022 06:15 am When looking at the zinc cents I often see diagonal lines on both sides. My question is about those lines. First they are not polishing lines correct? They are called roller lines (I believe). Did the mint purposely do that for the copper to have something to stick to? I was always curious.

jbuck Moderator United States 189767 Posts	Posted 02/08/2022 08:41 am I believe those are roller lines from when the zinc was rolled out. Similar process to the roller marks seen on later copper cents (the faux woodies). Here, the copper plating is thin enough to let them show through.

John1 Moderator United States 56855 Posts	Posted 02/08/2022 09:07 am I believe they are roller lines, but not from the mint. The mint out-sources the blanks. The lines do not help "adhere" the copper plating. John1 Report this Post to the Staff

BadThad Bedrock of the Community United States 19972 Posts	Posted 02/08/2022 4:33 pm These lines are present on all the copper plated zinc planchets (you have it backwards in the title). Look at this example or any other and you have your answer. https://www.jakesmp.com/Lincoln-Cen...p_20039.html Lincoln Cent Lover!

BadThad Bedrock of the Community United States 19972 Posts	Posted 02/08/2022 4:36 pm When the lines are not fully smoothed during striking (they are supposed to be) you have extreme example when a coin is lightly or poorly struck.
