I can see a nasty mark on the obverse

A lot of hairlines as well. Too many for AFDC.

Not quite as rare as first thought.  There are more than just a few known.

This is one of those varietals that seems once discovered that people look for it and find more and more. I love 20th C. proof halfcrowns but haven't had interest in picking one up at the prices they supposedly have gone for.

I'm quite happy with the price I paid for mine (£45).

I always smile at the phrase "visible under magnification" used by so many dealers. This always mean the marks are also visible without magnification. Marks not visible without magnification are of course (rightly) never mentioned by anyone.
