I agree Jerry but with the probable thousands of F10s around the world, we aren't going to get this analysis in a hurry. The fact that the new 2*+D is only (so far) found paired with reverse D* (curved rockline) suggests that it was not minted in huge numbers but then the fact that 3 of the known examples are around Unc suggests that there may be many of them, unless they were early strikings at a time when people were putting away shiny examples of the new-fangled bronze coinage ?
