I have this 1977 D penny am not sure if this is a error with the coin or if some one pressed this penny can you guys tell me what do you think about it please and thank you for your time
You have a cent where someone used a vice to squeeze another cent's image on to yours. It is an altered coin.
Welcome to Coin Talk. I agree with JCro57. Looks like a vice job. Stick around, there's a lot to be learned about coins from the members of this site.
