Ignorant Aussie Has Some Questions About Sheldon Grading System

Which coin are you talking about?

To me, that coin would be no better than F.

Let me know if it sells, I'll get my coins ready for ebay. :)

"Uncirculated" should mean that the subject coin has never been in circulation, and thus should exhibit zero wear, despite many other very minor problems it may have, such as tiny nicks and scratches

"Uncirculated" is a common term to all of the grading systems, so that should be a crossover point.
Unfortunately, that doesn't always seem to be so.
It seems that a coin with zero wear, but with very many small nicks and scratches would grade MS-60 or 61 Sheldon, but I have seen such coins return a grade of EF or good EF in the British grading system.
Thus
I am perfectly happy with the postulation that 'Unc' (British), equates to MS-62 (Sheldon)

I have often seen VF-30 Sheldon would even fail to grade Fine in the British system, and I think that is correct.

I have always understood that the term "FDC" (Fleur de Coin) means that the subject coin is absolutely pristine, which should equate to MS-70 Sheldon.

My attitude to all of this is to grade American and perhaps Canadian coins according to Sheldon, but for other than American or Canadian coins, I always use the British grading system,
because if other than an American or Canadian dealer describes a coin as "VF" for instance, I will trust that the "VF" grade (British) is is going to be at least VF-35 (Sheldon) or perhaps even higher.

The grading of ancient, hammered of milled coins is a separate skill, and is based on many other different considerations, that do not need to be taken into account with modern machine made coins, and perhaps should be discussed in another thread.
