Coinage metals
In the following a list of the abbreviations used in the catalogue:
| Au | Gold |
| Ag |
Silver (is never pure in coins for 100%, because they would be too soft) |
| NS | Nickel Silver (Neusilber) Alloy (45-65% copper, 10-25% nickel, 10-45% zinc) |
| Cu | Copper |
| CN | Copper-Nickel, alloy |
| Ni | Nickel |
| Al | Aluminium |
| Zn | Zinc |
| Fe | Iron |
| Ms | Brass Tombac: Brass alloy with high copper portion |
Partially the exact composition of the alloy is also given (e.g., for material tests). In this case Cu500 / Ag 500 means, for example, that the coin metal consists of 500/1000 coppers and silver.
