Thanks again I appreciate all the input. That coin I bought was initially on display at £56 so you are spot on. I have another issue, I had bought a couple of coins of John welsh who advertises in coin news. Having thoroughly checked his prices seemed the most reasonable. Has anyone dealt with him? is he an accurate grader? I have become a little worried since I came accross this: at http://www.goldsovereigns.co.uk/1821sovereign.html "Differential Grading As you can see, the 1821 sovereign we show in our photographs is a very nice coin. Even though we are professional dealers and not collectors, we get a tremendous amount of pleasure when we get to see, handle, own, buy and sell particularly attractive coins. It's sometimes called job satisfaction. There's also another bonus, we get to take photographs of these coins, and add the photographs to our collection; that way, even when we have sold the coins, we still get to keep the pictures! The third photo is of the coin in the holder which its recent owner made for it, and shows brief notes about the coin. These are quite revealing. They include: Grade; Gem BU . FDC by J. Welsh, Jan 1991. We assume the grader has followed normal convention by showing the obverse grade followed by the reverse grade. We have graded the coin as "About Uncirculated". The obverse has a few scuffs and bagmarks, which are all quite normal and acceptable. Circulation coins, which the Americans would call a "business strike", and handled in bulk at the Mint, and at banks, before they get seen by any potential collector or dealer. There is a noticeable scratch on the neck, and a few small edge knocks. There is also some purplish toning. The high points of the design have all got slight polishing or wear, so if we were being ultra strict, we might have to grade the obverse as only EF (Extremely Fine). To grade this as Uncirculated is therefore an exaggeration, to call it Gem BU is even more of one, firstly because "Gem" suggests "better than", whereas it is in reality "not quite", and the "B" stands for Brilliant (or Bright), whereas the coin is actually toned, which in itself is quite unusual for a gold coin such as a sovereign, and being composed of high carat (22) gold. We graded the reverse at the same grade as the obverse. John Welsh's grading states it to be FDC, which we understand to mean absolutely perfect, making this even more of an exaggeration than his obverse grading."
