BadThad Bedrock of the Community United States 19949 Posts	Posted 01/20/2008 12:06 am Any idea what this is? Hard to photograph because it's in an original proof set holder. Above the letters In God We Trust there are raised lines. They are raised from the surface, it's tough to see in the pics. I'm thinking about breaking the holder for better pics as these proof sets aren't very valuable. Lincoln Cent Lover! VERDI-CARE™ INVENTOR https://verdi.care/ Report this Post to the Staff

BadThad Bedrock of the Community United States 19949 Posts	Posted 01/20/2008 12:23 am Thanks. How come the surfaces are raised, most notibly above the S and T in trust? I understand the die cutting into it, but it can also raise the surface? Lincoln Cent Lover! VERDI-CARE™ INVENTOR https://verdi.care/ Report this Post to the Staff
foundinrolls Pillar of the Community United States 3507 Posts	Posted 01/20/2008 12:34 am yes, The pressure of the strike moves the layer of plating and the underlying metal outward. The metal will appear more raised near the edges of the coin. Also, when the die ejects the coin, the metal is moved upward and raised by the motion of the die coming away from the struck coin.
