Well from the pictures this appears to be a good candiate for what we call a GNL Class 1 Sheffield so I am not sure if weight and diameter will help?
If you look at the obverse this specimen seems to have that Sheffield ribbon seam from K-4/6 on the denticles (impression) that we describe in the new GNL Book in the Sheffield section.
The symmetry of the letters, motifs and date look good but that's consistent with most well produced Sheffields we suspect were made at the Tower Mint and/or other locations in London, England (due to their HIGH workmanship, Bordeaux Connection and other evidence).
I am at work so I can't tell if it's a GNL 1805 plated Class 1 vareity.
Between 1 & 8 it looks like some peeling is going on of the silver plate? - but can't be sure.
Good news if you are looking for a high quality Birmingham Sheffield CC8R this could be a good example which may be worth ~$100 today? If they are asking >$150 ... HMMMM.
Maybe Bob can chime in and give more of a certainty - also notice the row of double dentils in certain areas of the obverse?
If the edge has ONLY one overlap and not the two 180* overlap regal signature overlaps ... then its a Sheffield counterfeit.
Could be wrong. Pictures alone are tough to cherry-out Sheffields although this one has a high probability IMO.
We do see also a high amount of a reddish copper oxide coming forth - but from pics ... its tough ... need coin IN HAND.
Sheffields in high grades or in Mint State normally PEEL AWAY their silver layer along the rims and on the edge ... once you get the third side pic - take a close look ... these are two areas you can look at it and confirm for yourself on high graded specimens when you start going to lot viewings or big coin shows and seeing dozens of examples in AU or various MS grades ...
