1787 Sixpence
My guestimate: EF
I almost gave this GEF. While it lacks many of the finer details of the Pingo proof, I think this relates to die issues rather than wear. One of the first points of wear on these coins appears to be the tips and edges of the top laurels. There's next to no wear here on this example. I'm not sure if the lack of detail on the frills of his shirt around the neck relate to wear of or die issues, similarly with the bottom right curl of hair. The top of the reverse has a weak strike as does the Honoverian shield. The details in the Hibernian harp are excellent for a circulation coin. There are some hairline scratches on the obverse and flecking on the reverse. Good amount of remaining lustre.
I'm still having trouble differentiating between die issues and wear. I'm also having difficulty interpreting the reflections in images and determining how they relate to wear.
Feedback please!
btw, what value does Spink give to the various grades of a run-of-the-mill 1787 sixpence?
Edit: The seller has listed this as a 1787 Shilling. I believe that it's actually a sixpence because of
a. The extra detail in George III's hair to the left of the laurels and
b. The left of the base of the bottom of the hair-ribbon loop is squarer and consequently slightly closer to GIII's neck in the shilling than in the sixpence
I've asked the seller for diameter measurements in order to confirm.
