AH date bug [solved]

I've spotted a couple of coins including

where an entry of ND (no date) in conjunction with the AH calendar leads to an AD date of 622 appearing, thus messing up the order in which coins are listed. I'm guessing this is a bug in the conversion from AH to AD (treating ND as "AH 0"). Can this be fixed?

There is no bug just wrong input, ND is always in the Gregorian calendar.
The a few bits off on this coin page.

There shouldn't be place holders like X but what is depcited on the coin picture, the side description is not for the coin text and lastly the Note should be put in the comment section. /preaching

At least that are my two cents on coin pages.

The dates for the ND entry have been updated to the Gregorian years, but there is still something wrong. I will check that.

​i think its a matter of server update?

Hello,
This is fixed

The following coin

is also suffering from this problem. Do we need to change how undated coins are listed to avoid it?
