So, I am currently inventorying my foreign gold coins, and decided to select a few of the more interesting and/or challenging graded coins I have to put up for the community to give their 2c worth... Grade Challenge #2 -> 1648 Spanish Netherlands 1SD'OR TOURNAI - You VS NGC -   |

Have a look at the grading standards for ancient coins,
Google: 'NGC grading standards for ancient coins' (quite involved),
then offer a grading opinion.

@ sel_69l
I am unsure sure if that is directed at me or as a general heads up, but I have the coin in hand and it is already graded by NGC (I am also familiar with the grading standards for ancient coins)... I was simply curious what others might guess it's grade to be (as determined by NGC).

A general heads up, so that we may all learn a little more about grading medieval and ancient coins.
The grading techniques and standards are quite different to grading U.S. coins via Sheldon.
-----------------------------------------------------------------------------------------------------------------------------------------------------------
I tend to shy away from the term "mint state" for medieval and ancient coins.
The nearest grading you can get to a coin freshly struck is 'AS' (As Struck).
Even then, such a coin may have significant die, flan and striking problems. If coin has no such significant problem, it is about as rare as a hen's tooth.
Thus, each medieval or ancient coin is unique in itself, and uniqueness is not a guarantee of great value.
Nevertheless, a higher NGC grading does loosely factor into the value.

Okay, this one is obviously not all that popular... When I have better light (hopefully tomorrow) I will snap some shots of the full slab to reveal the grade.

AU55/Ch AU?
Strike: 3/5
Surfaces: 4/5
I've never seen one before so this is an educated guess

1. NGC gives regular Sheldon numbers to world coins from this era. And tend to be generous, taking into account the various imperfections in the minting process. I have posted on this previously, and @sel has helped educate me. 1a. I would even go so far as to say there is significant economic upside to exploiting this in the current market if you have the capital and know what you are doing. 2. Wow!  I would have guessed at least MS63 based on lots of other material I've seen from this era, but it looks like it's quite a bit lower ... reinforcing that I don't know squat about grading.

If I was a lot describer for a specialist numismatic auctioneer, I would grade this coin thus:-
Lot XXX:- (coin description:-) '1648 Spanish Netherlands 1SD'OR TOURNAI'
obv.:-Crowned loin rampant with sword, in globe in dotted border, legend around, date below in exergue,
rev.:- Crowned shield in dotted border legend around.
'EF, weak strike in parts, some edge clipping. (P)'......................(estimate $XXX)
(P) means that it has been photographed in the auction catalog.
EF (British grading), would be an overall inclusive net grade, but comments are still needed to accurately describe the lot.
----------------------------------------------------------------------------------------------------------------------------------------------
Even so, it is still up to the intending bidder to examine the lot, and grade for himself.
Different bidders would place different personal emphases on different aspects of the grade, to decide on a bid price.
With experience, this grading and valuing process becomes relatively simple.
