In the February 2011 issue of “World Coin News” there is an article titled “Brunei changes, composition, weight of 5-cent coin”. I will paraphrase or quote some of that article.
In 1967, the Brunei dollar replaced the Malaya and British Borneo dollar following the formation of Malaysia and the Ringget was exchangeable at par until 1973. After 1973 the Monetary Authority of Singapore and Brunei Currency and Monetary Board retained exchangeability of the currencies.
Under the current agreement neither currency are “legal tender” in the other, however each are accepted by agreement and the author called that “Customary Tender”.
I have never heard the term “Customary Tender” although I assume the situation it refers to is not that uncommon?
Anyone know of others were the currency isn’t legal tender but is accepted? And not just accepted (that happens all the time) but accepted by governmental agreement?
