I am working with a shapefile with a jagged coastline and interior regional boundaries. I am trying to create a thin line for the coast, so it appears more clearly, while still keeping bold, thicker lines showing the interior regional divisions. Normally I would just rearrange the drawing order, but because the interior lines need to be thicker, they just overpower any thinner lines. How can I create a thinner coastal line while still keeping a thick interior line for these polygons? Thank you!!!

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
Make 2 copies of your coastline layer, then below that put your interior divisions layer. For example:
On the top Coastline layer, make the border a thickness of 1 (thin) and whatever color you want.
On the second Coastline layer, make the border a thickness of 3 (thick) and make it white (or whatever color your background is.
On the InteriorDivisions layer, make the border a thickness of 3 (thick) and whatever color you want.
This should (mostly) achieve what you want.
I don't know what software you're using, but in ESRI, you could DISSOLVE a copy of the original shapefile. This would leave you with an outline of the area (which you could make thinner).
Then ... convert the polygon shapefile to polylines -- SEE THIS LINK and delete the outer edges in an edit session so you can leave the interior lines thick.
I am assuming there's no analytic component to your project.
Shouldn't take very long -- Good luck
