20 and 25 as denominations

[Figleaf]

The NFL$ was actually Spanish colonial pesos/8 reales, but they had a different rate in the US and Canada. Canada just copied US developments, while NFL followed UK colonial policy. Before 1825, the NFL$ had a rate of 5 shillings. Afterwards, it was fixed at 4s 4d currency. The word currency is important. The currency pound was set at 17/4 sterling (UK money) or, a pound in coins was worth 1/3/1 currency. The rates were tinkered with further until in 1887 (50 Vict. cap. 4) the pound currency was deleted as intermediate reference.

The story is different for gold. Newfoundland adopted the gold standard in 1863, after Canada had done the same. It rated the NFL$ gold at 5 shillings, so 2 dollars gold was not the same as 2 dollars silver when expressed in sterling.

Source: A History of the Currency in the British Colonies by Robert Chalmers (London, 1893). There's much more detail in the book on NFL$ as well as the reforms of 1825, which were meant for all British colonies.

Imperial germany tried to introduce both coin types, 20 and 25 pfennig.

20 Pfennig (Silver) KM#5, 1873-1877
20 Pfennig (Copper-nickel) KM#9, 1887-1888
20 Pfennig (Copper-nickel) KM#13, 1890-1892

25 Pfennig (Copper-nickel) KM#18, 1909-1912

All this coins were very unpopular at the people, therefore no official attempts to introduce
20 or 25 Pfennig pieces were made until the euro came in 2001.
Exceptions exist in the inflation time between 1918-1923 and in the FRG (20 Pfennig 1969-1990).

A remarkable coexistence of two near denominations is the 4 Pfennig piece of 1932 (KM#75) as a 5 Pfennig piece (KM#39) was issued the same time.
It should have prevented price increase in the years of the great depression!
People in germany did not liked that coin verry much and called it "Brüning Taler"
or "Armer Heinrich" after Reichskanzler Heinrich Brüning who was made responsible for its introduction.

Ah, but Germany never had 20 and 25 Pf coins at the same time.   Agreed, neither denomination was really popular. The GDR, however, did have a 20 Pf coin from 1969 until 1990. Primarily for payphones (the aluminum pieces would not work there) but it was in regular use ...

You are right, sorry i ment the GDR not the FRG 20 Pf. 1969-1990.
I am not used to those abbreviations in common use as we use DDR and BRD in germany

Supplement to Czechoslovakia!
Second republik had a 20 Haleru denomination first in brass 1947-50 KM#20
later in aluminium 1951-1952 KM#31.
People's republik changed the denomination to 25 Haleru, 1953-1964, aluminium KM#39.
In 1972 again a 20 Haleru piece, KM#74 was issued in nickel-brass, later in aluminium-bro, as a heavier coin was needed for the use in public telephones. All coins under 50 Haleru were from aluminium and to light weighted for the machines at that time!
This type was in use through all the years and political changes in 89-91, til the split of the czesk and slovakian republiks in 1993.
