The information of chapter 9 has to be repected especially for silver alloys.
Type A
Investment gold bars (Degussa, Umicore, Heraeus, Agosi etc.), Vienna Philharmonic, American Buffalo,
Kangaroo Nugget, Maple Leaf, China Panda, Mexico Libertad, Australian Lunar, coins Germany (100 marks
collector coins etc.), UK Gold Britannia (since 2013), Spain 5000 to 80000 Pesetas
Type B
Please note: The target value is a compromise between the actual target value of the 986 alloy for objects
thicker than 1 mm (25.5 MS/m) and the 1&4 ducat coins Austria and their restrikes (27-29 MS/m), which are
almost exclusively used in practice and are very frequent - these are special because they are very thin (0.71-
0.75 mm) and therefore below our regular minimum requirement of 1 mm.
Type C
South Africa Krugerrand, UK Gold Britannia (1987-89), Canada 100 dollars, Turkey 100 piasters, Australia 200
dollars Gold Koala, UK Sovereigns, Chile 5 pesos (1895-1980), 20 pesos (1896-1917), Peru Libra (1898-1969),
