I agree with Stuntman, the grade seems ok, don't know the price, eye appeal is in the eye of the beholder. You get flecking in early milled silver of this period (due to metal composition) but not normally just in one place. Check with the dealer/seller that you are buying 'on approval', i.e. you need to see it in hand and will return for full no quibble refund if you are not happy, and that they are happy with that.
For me, I just want a decent LIMA George II halfcrown, not both a 1745 (with the U instead of V in GEORGIUS, which I'm guessing was in error), and a 1746, just the one - this is my best so far -
a few years ago these could be bought in a high grade for a fraction of what they go for now, wish I collected seriously 10-30 years ago! But there we are, still fantastic examples are available of many coins at good prices if you do your research and show patience
