Currently Numista cites the various dollar-denominated banknotes issued in some territories such as Barbados, British Guiana etc. as simply “Dollar” with no additional details. In my opinion this needs qualifying with some such description as:
1 Dollar = 4 Shillings 2 Pence • 4 Farthings = 1 Penny • 12 Pence = 1 Shilling
In these territories the Spanish Dollar was used as the main unit of account for over a century after actual Spanish Dollar coins disappeared from circulation, the coins used were standard Sterling issues; pennies, shillings, half crowns and so on (except for special cupronickel issues for Jamaica, where the locals were not keen on copper coins), with the Spanish Dollar having a fixed value of 4 shillings 2 pence; that being 100 halfpennies. It wasn't until 1955 that specific cent-based coins were issued.
I would be happy to hear what anyone else might wish to add.
