I am Posting a this picture of an error penny, Novice to this, this penny seems to be a major error. Just looking for feedback. Picture should not need to be explained I hope.
See how the lettering is backwards? Your coin had another coin pressed into it outside of the mint. Not an error.
Welcome to CT! First, you need to provide a clearer photo. Just by looking at this photo my best guess would be either counter stamp cent or a vise job. Its PSD (Post Strike Damaged).
So part of the capitol building along with the letters T and N stuck on the front is not considered an error?
Firstly, it's the Lincoln Memorial. Secondly, no it is not an error. Someone did it after it was minted. It is considered damage.
Ok my bad on the building, I knew that....doesn't help me not look stupid though. I have been looking at coins for only about a month. help me with this please, I have several pennies with extra bubbling and or bumps, not sure what they would be called. I do have several 2018 pennies with I guess they are called chads. I will post some pictures later but just want your thoughts.
Sounds like you are describing plating blisters. Depends on what year the coins were minted. Anything post 1983 are copper plated zinc and are subject to plating bubbles. I've never heard the term "chad" used in numismatics. The last time I heard that word used was in reference to George Bush and Al Gore I think the word you are looking for is either CUD or die chip. Those are breaks in the die. A CUD will start at the rim and move inward on coin. A die chip will be a, usually, small break along a certain design element on a coin.
