I have 3 1982 D Penny's. All three look different to me. But I think I been staring at the number 2 to long. And can't tell any difference now. Some fresh eyes and someone who knows what they are looking for would be really appreciated.
All of your Pennies are Large date. This picture and then one provided to you before will show you the difference
If there are any differences, it could be weight. It's important to weigh any coins you have questions about. Zinc cents weigh 2.5 grams, copper 3.11 grams. In 1982 they made both types.
