Same diameter as all other issued coins

Still learning the terminology to explain
properly but couldn’t figure or find the raised area on this coin.
Thank you for stopping by.

I think this one was in a metal bezel, one of those tin things that says something like "lucky penny" with and ad.
Someone pried it out.

Now you see an outer area of the rim that's flattened then just inside of that you see a raised area (on the obv) which is where the opening of the holder was.

Like this coin in this thread but on that one it shows best on the rev, yours shows best on the obv.

Probably a bezel of some kind like Ed said.
(Bezel-Juice, Bezel-Juice, Bezel-Juice! Sorry, I just couldn't resist.)

I agree with the bezel scenario.

Nice... A formerly encased coin... This is from our Glossary -

Encased Cent (Ex-encased Cent): A cent that was once kept in a bezel as a piece of jewelry or “lucky” cent. Many of these ex-encased cents will exhibit damage in the form of a flattened rim from the bezel they were in. Pictures courtesy of forum member mrmike916.

Here is a web site I came across http://www.encasedcoins.info/

The normal wire bezels like the one in the pic don't do much damage, they're like a channel, they wrap it around and solder the ends to close it.
It's the lucky coin clamshell ones that make that double/flattened rim.
