Possible 1982 D Small Date

Nope, it's just the normal Large Date Cent. https://www.lincolncentresource.com...es/1982.html

This is the one you want to look for. It's the 1982 Denver Small Date copper cent. https://www.numismaticnews.net/worl...t-discovered

Try to find an actual small date.
This will allow you to have an actual small date to compare it to.
My guess is you are hunting the way most people do.
1) Find all the 82 Ds you can
2) Weigh them to find the 3 g coins
3) Then you try to determine if the 3g coin is the small date.

Doing this guarantees you will only be looking at large dates. You will never learn what a small date looks like because you never looked at one.

What you should do is grab the 82s then sort them by large and small dates. Once you see them side by side in hand it will be easy to tell the difference.

I have pile of small date 1982 D pennies.
But they are all the wrong weight.
