1983 LMC Obverse Date Die Chip?

First,

Nice find! There is a known interior die break on 1983 cents. It is listed as IDB-1c-1983-04 on cuds-on-coins.com. The break closest to the "8" on your coin has a slightly different shape, and appears to have a slightly different point of connection to the "8." The other breaks on your coin look like a continuation of the initial break.

Wait for some of the others to weigh in on this, but I think you either have a later die state of the known IDB or you may have a new IDB for the date. Either way, it's a keeper.

@coop, take a look at the enhanced photo I just uploaded. Your analysis makes me pause on my first assessment.

It's possible that two different things could be going on here. The bump attached to the 8 is extremely similar to the known IDB. The second higher bump has a similar appearance. That said, there is gray visible at the base of both lumps. The more circular device that runs through the 9 and 8 appears to be something different, and could well be a plating bubble. I'd love to see a lower angle shot of this.

The best way to tell is to look under the plating to see if you see copper or zinc.
Copper = Struck through
Zinc = split plating.

I wonder if the loose plating is already curling?

I use something like this to make the light hit the coin and direct the image into the scope:
