These coins were available via Chinese e-commerce websites for a while in quantities of between 10 and 200. The first design to appear was the 2015 Royal Navy (Presumably fueled by the media interest in the 100 4th portrait coins released into circulation) and it snowballed from there. Were prevelant in the Swansea area but are widespread now. There are a few subtypes but not enough to go into detail here.
Earlier (and or cheaper) Chinese copies. The 2008 version also originating on a different Chinese e-commerce site. The coins are in such high relief that they're easily spotted. Seemed centered around the Bradford area. Unsure of the newer ones that have started turning up (Slave Trade etc) but all the coins in this category are certainly not the same calibre as the main Chinese coins above.
