Edinburgh was the main Scottish Assay Office.
Edinburgh’s marks consist of:
Maker’s mark
Town mark, (three castles)
Thistle
Variable date letter
Duty mark, (from 1784 onwards)
The rules were not always strictly followed
when it came to hallmarking sugar tongs. Either the thistle or town marks
were used on a fairly random basis. This means that a pair of sugar tongs
could be marked with either the thistle or the castle, but rarely with
both. The date letter was not used until quite late. Very often multiple
marks are punched, either the maker’s mark several times or the thistle.
This is even more noticeable with the provincial towns. There were a number
of Edinburgh makers and I have shown tongs by them below.
If you are looking at collecting Scottish Provincial
work, bear in mind that it will often be hall-marked with Edinburgh marks.
