Coin: Twenty Cents 1991 (mint sets only)
Description

With the introduction of decimal currency on 10 July 1967, the new 20 cents denomination was equal to one florin (two shillings) of the earlier pre-decimal currency. The two coins were identical in size and florins remained in circulation (and legal tender) in parallel with the new coins until they were both demonetised in 2006, when a smaller twenty cent coin was introduced instead.

Twenty cent coins were only issued in mint sets in 1991 (not intended for circulation); any that were released would have circulated circulated for 15 years before they were demonetised on 31 October 2006.
