1. Norges Mynter - The Coinage of Norway

Bjarne Ahlström, Bernhard F. Brekke, Bengt Hemmingson, 1976

Norwegian coins from 995 to 1975

We have Norwegian coins from 995 to 1992 https://en.numista.com/catalogue/catalogue.php?id=2786

Do they share same numbers? 

They do not share the same info, only one author is same.

The 1976 book has more detailed information and and variation description. It also has patterns and some coins that the 1992 book does not.

What should be the codes for these catalogues please?
