scrounger1 New Member United States 4 Posts	Posted 11/28/2023 1:25 pm Hello, All! I'm new to the coin community, and I'm excited to start sharing and learning. This is a 1990 no mint mark penny with what looks to be doubling from die fatigue (my best guess). I'm wondering if this is a decent find, or if this is a pretty common mistake. The last two photos are washed out, as the relief is way more refined than the photos. I'll be working on a better photo studio. So thanks for your understanding, as this is my first time photographing coins. And thanks for any feedback! Edited by scrounger1 11/28/2023 1:35 pm Report this Post to the Staff

John1 Moderator United States 56855 Posts	Posted 11/28/2023 1:55 pm scrounger1, I see a plating issue. Looks like trapped gas under the copper plating, somewhat common. No added value. John1 Report this Post to the Staff

Second, yes it looks to me like the copper plating was so thin that a little bit of the zinc core was exposed and has now started to deteriorate. I'm pretty sure that only one doubled die for this year/mint is known.
