I'm new to 3D modeling and especially to getting my UVs unwrapped. Currently, as seen in the screenshot below, I appear to have a whole slew of faces (54, I believe) that cannot be seen, nor do I want them to be seen. I'd like to get rid of those faces, but I can't seem to find them to select - as if they were inside the geometry. Is there are easy way (or heck, a complicated way) to find and remove these faces?
I'm also not sure what those long triangles are that are on the front and rear surface of the coin. The edges are uneven purposefully - the edges were extruded some to give it a very uneven feel. When I select a face on the UV window, no part of it looks particularly strange.
The shape changed, but now I have these two rings (I have them lying atop one another currently while I was trying to figure it out) that don't seem to be visible faces, but increase the face count by more than double. I believe I should have 34 total faces. So this and trying to figure out why my UV unwrapping doesn't seem to go into the export file. Oy!
