N#125357

Years: 882-913 (622-1514)

What is 622?

622 is the Gregorian date for 1 AH.

 

There are also other problems with the range.

The type has ND (1466-1514) and 882 (1478) through 913 (1508) .

 

The summary range given is 882-913 (622-1514). The end points of the range don't match. The Hijri date of 913 at the end of the range corresponds to 1508.

 

The range in the years field should be 871-921 (1466-1514).

 

I think the root of the problem is that the ND dates are always AD, and aren't converted to AH for use in calculating the range of years in AH.

Are there really ND issues or is it just a stand-in for coins with date off-flan or that are too used. If it's the later that line should be moved to ‘Undetermined’ anyway.

The same would apply to the Qrim mint coin.

Yes, this one seems to be with a full flan, but without date: https://www.zeno.ru/showphoto.php?photo=243143

Technically solved for the 622.

 

Date inconsitency still to be fixed with ND overlap.
