1858 10 Cent ?

I looked at the 1858 on the C and C website. The nose could be do to the wear of the coin and the letters of Canada look the same, the "A" seems to be dropped out of line

It could be wear, but the serif's just don't look right on many of the letters, C in victoria, E in DEI and many others. I am looking at charleton's, but this is not an area I am too familiar with. Perhaps some of the others know better.

I think it's a sharp cut at an angle as well. Especially in the forehead are. The last resort is to get even closer and clearer pictures, because I'm not convinced its a defaced die, rather the coin itself is defaced. It's a bit of an optical illusion, because the line is raised, but from from sharp cuts, just my opinion.

I am now convinced it is PMD. 1--The line shows a furrow besides and almost under the line. 2---Notice the darknes besides the line, even though other shadows do not show on the face. 3---the line follows roughly the contours of the face. 4---No other examples on 10c like these. 5---Possible cutting tools could be razor blades or Xacto knife. 6---The line is not worn at all, as compared to the coin general wearage. The PMD is later than the mintage date. 7----The line is the exact hue of the silver coin itself, therefore silver itself. 8---I'm willing to put money where mt mouth is.9---The line does not extend under any legends.
