I found this in Bank of Jamaica:
Since 2011, De La Rue International Limited and The Royal Mint are no longer the sole printer and mint for notes and coins, respectively. A competitive tender process was implemented to select printers and mints in a given year for each banknote and coin denomination. In that regard, successful printers to date for banknotes are De La Rue International Limited, Giesecke and Devrient Currency Technology GmbH and Oberthur Fiduciaire. For coins, successful mints to date have been, The Royal Mint, Royal Canadian Mint, Royal Dutch Mint and Mint of Finland.
Effective 15 February 2018, the $0.01, $0.10 and $0.25 coins were demonetised. Consequently, the $1.00 is the lowest coin denomination effective 15 February 2018.
It's based on this communication on the WoC web site: http://www.worldofcoins.eu/forum/index.php?topic=57555.new#new
Maybe Peter can look into that, since only the royal mint is mentioned in numista? (Royal Mint, Llantrisant, United Kingdom (1968-date)
