We can see that the difference in weight and material are the main characteristics and it’s also interesting to show the difference in value of Phan multiples. The difference in weight is much easier to classify than the difference in diameter.
I get the 3 Phan coin in my collection so I’ll create KM#182b.
I’ll let you modify the 9 Phan and 6 Phan pages in English and French.
The current comment for the KM#182a : “This type was weighted to 6 Phan, which was worth two zinc coins” looks incorrect if we consider that the zinc version was a Phan.
In the title, you may differentiate the three different set of copper coin by value 9 Phan, 6 Phan, 3 Phan or/and size: Large, Medium, Small
And Inside each file I would recommend to let only one line, but not create sub Numista numbers as N#36427.1, N#36427.2 which brings confusion.
An alternative more complex could be to add a line for each Barker varieties, but again, that might lead to confusion for the collector who don’t get the Barker book.
In comments, the reference to SCOTT SEMANS WORLD COINS – VIETNAM CASH should be added in both French and English coin pages versions.
Once again, sorry for the mess I caused with my insufficiently precise change request.
