The last British Groat (Fourpence) coins minted for general circulation were issued in 1855. There were Proof coins minted in 1857, 1862 and 1888. The Groat does not seem to have been officially withdrawn from circulation at any time and was still being used in some ceremonies well into the 20th century. Circulation of the Groat just seems to have declined as most found their way into coin collections. The Groat has continued to be produced as part of the British silver Maundy set, an annual ceremony which continues to this day. The Groat is no longer circulated since the silver content and numismatic value of the Maundy coins far outweigh their face values.
