Jblau190 Valued Member United States 78 Posts	Posted 06/16/2023 12:10 am So I'm still very new to this stuff and often see coins with this type of doubling. I assume it's MD but hoping DD lol. I know DD is supposed to widen the device while with MD, the devices usually remain same size as normal. Figured worth asking you guys so I can get an accurate answer and whatever tips and advice anyone might have. Thanks in advance! Report this Post to the Staff

Spence Moderator United States 34428 Posts	Posted 06/16/2023 07:04 am @jbl, if the doubling is shelf-like and serves to reduce the width of the letters, then it is Machine Doubling as @sil stated above. Also, for your next thread, please include the year and mintmark as this helps with the CCF search functionality. Thx!

Jblau190 Valued Member United States 78 Posts	Posted 06/19/2023 01:26 am Im sorry, I had taken these pictures while sorting through an examining several hundred if not thousand pennies I have so I assumed it was Machine Doubling but posted these specific photos as an example as I see many Lincoln Memorial pennies with the same double like appearance. In fact, I see this type of doubling so frequently that I knew it couldn't be doubled die error by the frequency of this type of characteristic on man pennies I have examined. I didn't put this specific coin aside or make a note of what year and mint it originated from so I can't help with giving more information or photos at this time as I just was looking for a definitive answer on what this style of doubling would be considered and not this specific coin. You guys verified my thoughts but it's good to hear it from more experienced and informed people from this form as that's how I've obtained the majority of my knowledge thus far. Thank you guys appreciate your help as always. Report this Post to the Staff
