An Undecimalised Decimal Currency
Sirocco uses the simoleon (§, SRS) as its currency, which is unique among micronations as it is not based on a clean 1:1/100 ratio, such as the New Zealand dollar, which has 100 cents to the dollar. Instead, Sirocco uses a decimalised version of the former British pounds, shillings, and pence, which were used in South Africa and New Zealand until 1961 and 1967, respectively. Under this system, there are ten baud (pronounced 'bored') to one shilling, and ten shillings, or 100 baud, to one simoleon.
The simoleon formerly used a fully decimal (1:100) system between 2008 (GDR simoleon) and 17 February 2014, when it was replaced by the current 1:10:10 system.
Sirocco uses the baud (1b), two baud (2b), five baud (5b), shilling (1/-), two shilling (2/-), five shilling (5/-), simoleon (§1), and two simoleon (§2) coins.
Sirocco uses the five simoleon (§5), ten simoleon (§10), twenty simoleon (§20), fifty simoleon (§50), and one hundred simoleon (§100) notes. In the past Sirocco has used §200 and §500 notes, although these were demonetised in 2015 and 2012, respectively.
Sirocco's current banknotes, featuring important Siroccan political figures, were introduced on 4 November 2015. Its former banknotes, introduced in May 2012, were demonetised on 31 December 2015.
Working With the Simoleon
The simoleon uses a writing scheme very similar to that of the £sd system.
But if you want to get really involved with the simoleon, learn the alternative terminology - 'bit' for baud, 'bob' for shilling, 'quid' for simoleon, and 'shilling-and-baud' for units like 4/2 ('four-and-two'). Sure, it might seem silly now, but when someone asks to borrow "three quid nine and six", you know how much they want you to lend them (§3 9/6). Whether they pay you back or not is another story.
