Tacc Pillar of the Community United States 3535 Posts	Posted 02/10/2023 2:16 pm Found this coin in change yesterday. It's very ugly. I almost feel sorry for it. My ? #1: Is the Obverse missing almost all of the copper layer? Note the area around the date being copper & shiny ? #2: what is all the rough surfacing on both Obv & Rev. Die Cud?

Tacc Pillar of the Community United States 3535 Posts	Posted 02/10/2023 3:52 pm Cool thank you guys. I would like to learn more about Die Cud errors. Any choice reading on this error type? I did look for Cud in the left hand of home page as John 1 suggested but didn't find anything. I may just need more guidance in the use of this website. Report this Post to the Staff

John1 Moderator United States 56855 Posts	Posted 02/10/2023 4:02 pm http://www.error-ref.com/ http://cuds-on-coins.com/ From the Glossary: Cud An area of a coin struck by a die that has a complete break across part of its surface. A Cud may be either a Retained Cud, where the faulty piece of the die is still in place, or a full Cud, where the piece of the die has fallen away. Retained Cuds usually have dentil detail if on the edge, while full Cuds do not. John1 Edited by John1 02/10/2023 4:04 pm Report this Post to the Staff
Tacc Pillar of the Community United States 3535 Posts	Posted 02/10/2023 4:12 pm OK I found Numismatic Glossary now! Thanks again. Even after collecting coins now for 50 years, the whole ERROR thing is new to me and little overwhelming, BUT FUN! Report this Post to the Staff

merclover Bedrock of the Community United States 10635 Posts	Posted 02/11/2023 05:19 am If it was missing all or part of the outer the exposed area would be grey, not shiny copper. The zinc core is grey in colour. Report this Post to the Staff
