It seems they have a smooth surface. Thats a sign of injection molded in my opinion.
Also, it looks again from the picture that the inlays are stuck on the chip rather than being 'within' the chip.
With compression molding the inlay goes in the mold. It doesnt produce the same end result.

Look at the irregularities around the edge of the inlay and compare that to your Paulson Classics and you should see what I mean.
