Accendo New Member United States 1 Posts	Posted 01/08/2026 02:23 am Hello, I happened to find in my coin jar a 1989 D Penny, and weighed it on my digital scale and it displayed 3 grams (3.1?). I recently learned that this Penny is extremely rare and would be grateful to know if this is indeed the Penny that I have. I've included a picture, and have not cleaned the Penny which you can see is not in mint condition. I used the CoinKnow app to take the picture of the front & back. I'm a newbie to all of this so thanks your patience with me in advance! Grateful for any help, and will be much appreciated! Report this Post to the Staff

Can you provide us an image of your scale with the cent on it please? Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.
