Double Denominations

[a3v1]

Assumptions correct! For some time the Belga was just the name for an equivalent of five Francs.

Wikipedia says:

In 1926, Belgium, as well as France, experienced depreciation and an abrupt collapse of confidence, leading to the introduction of a new gold currency for international transactions, the belga worth 5 francs, and the country's withdrawal from the monetary union, which ceased to exist at the end of the year. The belga was tied to the British pound at a rate of 35 belgas (175 francs) = 1 pound and was thus put on a gold standard of 1 belga = 209.211 mg fine gold.

However, the idea didn't catch on and in 1935, following great hardship during the crisis of the thirties, the Belgian franc was devalued by 28% to 150.632 mg fine gold, which broke the link with the pound. Thereafter, the Belga was abandoned.

Portuguese India, 1871.  One tanga = 60 Réis.

Newfoundland, 1882. TWO HUNDRED CENTS / ONE HUNDRED PENCE / 2 DOLLARS.

Remember that Britain didn't have decimal currency in those days, so the 100 pence equalled 8 shillings and fourpence.

Another one: Bolivia 1893 : 1/2 Boliviano / 50 Centavos

The predecimal, pre-1871 currency of Prussia included numerous coins of the type illustrated below:



This one is 1 pfennig or 1/360 taler; I have similar bronze coins denominated as 2 pf and 1/180; 3 pf and 1/120; and 4 pf and 1/90.

The silver coins have a similar double denomination:



2½ Silbergroschen = 1/12 taler; I also have 1 Silbergroschen = 1/30 taler.

These double denominations show how versatile non-decimal currency systems can be in terms of being divisible by the maximum number of factors (360 is even better in that regard than the UK's 240), but equally the fact that the coins had to show the conversion rate implies that there was some confusion or difficulty on the part of users.

Naya paisa series had both paisa and rupee mentioned on it...I am not sure this will fall under this thread...

Those are fine coins, but I would not actually count them as double denomination pieces. As you explained, the value is simply expressed in two different ways - it's as if a modern British 20p coin said "TWENTY PENCE - 5 ONE POUND". But maybe I am just a little too strict here.

How about a banknote with double denomination. 1915.
The Dardanelles Campaign Overprint, 10/- or Piastres silver 60 and Piastres silver sixty.

Agreed, but they're along the same lines as the Belga coins illustrated upthread.

Didn't realize that, but it makes sense, of course. Can you help with the exact text, Vivek?

The coin mentions 1 Naya Paisa (center), 1/100th part of a Rupee (on the edge).

As the originator of the topic  I simply meant that the denomination should be expressed in two (or more!) ways: so 10 cents and 1 shilling goes, as does (one I posted earlier) two hundred cents and two dollars. 

[chrisild]

Ah yes, then those examples do make sense here. Even Peter's "100 C" gulden. Which is somewhat strange by the way; I know they started doing that in 1815 but for some reason with the 1 gulden coin only. Does the 2½ gulden coin say "250 C"? Nah ...
