20 piastres, Sudan aH 1311/11
« on: January 11, 2011, 02:38:54 PM »
Hello.

These coins were made with a mixture of silver and billon, seems to have a higher concentration of silver, which I raised some questions according to information from Krause, where in 1311 should have a lower concentration of silver. These coins were sometimes made without great accuracy in metals, krause may be exposing a less precise information. What do you think? A clarification, aH year 1311/11. The Christian year that corresponds?

The AD date is 1904 ( if my maths is right).   Are you saying the coin has a higher concentration of silver than recorded in Krause. If so one possibility is that the ubiquitous Maria Theresa Thaler was the source of silver for these coins.

The AD date is 1904 ( if my maths is right).

The AD date is 1894 - if my maths is right. ;-) At this coin the date AH 1311 is not the accession date, but the actual minting date.

The coin has the typical billon look for this type and year. There is nothing special. The middle coin is exactly your variety of three (known to me) for this year in this type.

But it is not so easy to find. Gratulations!

Thank you for the reply. The detail of the data was confusing me.
