Back in distant 2011, you featured the 1841 three pence coin found in Australia. I asked the Royal Mint at the time if they knew where the normal "Colonial" strikes went and they have only just replied! However the information may still be of interest. I was surprised how many overseas locations took them - the Spink Standard Catalogue merely says "for colonial use".

(1) Circulating threepences were produced bearing the date 1841, as well as Maundy pieces;

(2) The two types bear identical designs and thus can only be distinguished by the quality of the finish. If a Maundy coin were to enter circulation, it would soon lose its distinctive quality.

(3) Mint records suggest that about 440,000 circulating threepences and just under 3,000 Maundy threepences were struck in 1841.

(4) As for the colonial destinations, Mint records from the 1830s and 40s show that threepences were ordered and sent to such places as Jamaica, Bahamas, Barbados, Berbice, Grenada, Antigua, Demerara, Sierra Leone, Dominica, Mauritius, Malta, Gambia and St Helena. With respect to the 1841-dated pieces, there is reason to suppose that some if not all of them went to Mauritius.

Google tells me Berbice was merged with Essequibo & Demerara to form British Guiana in 1831. I have to admit I hadn't heard of it !
