1698 William Coppers

They are buggers to get above F..when grading don't lower your expectations and don't believe blah blah grade for issue.All 3 coins are Poor/good at UK standards and I would certainly be sitting on my hands.

EF is quite right, 1698 is a difficult date to find for both the halfpenny and farthing so examples in any grade can be deemed acceptable. Although I also agree with Peter that they almost never appear in grades above Fine, personally, I would prefer to have a lesser grade example than none at all. There is always the option of upgrading should something better come along.
For the 1698 halfpenny the 'date in exergue' is the rarer of the two types being coined for a couple of months only. Here are two specimens I have. Interestingly you'll note they are struck from two different reverse dies.

I'm pleased you like them EF.
I've just checked ebay for the coin referred to in your post. Wow, that's ugly. I know they're hard to come by but, even so, the asking price is silly for such a poor specimen.
