Stanchester Hoard: The Stanchester Hoard is a hoard of 1,166 Roman coins dating from the fourth to early fifth century found at Wilcot, in the Vale of Pewsey, Wiltshire, England in 2000.  The find was considered important because of the large quantity of unclipped silver coins contained within.  It was also the latest dated example of Roman coins found in Wiltshire.

Rogiet Hoard: The Rogiet Hoard is a hoard of 3,778 Roman coins found at Rogiet, Monmouthshire, Wales in September 1998.  The coins dated from 253 up until 295–296.  The hoard notably contained several faulty issues, and some rare denominations, including those depicting the usurper emperors Carausius and Allectus.

Shapwick Hoard: The Shapwick Hoard is a hoard of 9,262 Roman coins found at Shapwick, Somerset, England in September 1998.  The coins dated from as early as 31–30 BC up until 224 AD.

Ubouzanes: Ubouzanes was a ruler of the remnants of the Indo-Parthian Kingdom in Arachosia in the first century CE.  He was the son of Orthagnes.  He was unknown until the late 20th century when a hoard of coins was found in Jammu.  Joe Cribb first analyzed them in 1985, discovering some belonged to a new ruler.  Cribb placed him between Orthagnes and Pacores

Indo-Parthian Kingdom: The Indo-Parthian Kingdom was ruled by the Gondopharid dynasty and other rulers who were a group of ancient kings from Central Asia that ruled parts of present-day Afghanistan, Pakistan and northwestern India, during or slightly before the 1st century AD.  For most of their history, the leading Gondopharid kings held Taxila (in the present Punjab province of Pakistan) as their residence, but during their last few years of existence the capital shifted between Kabul and Peshawar.  These kings have traditionally been referred to as Indo-Parthians, as their coinage was often inspired by the Arsacid dynasty, but they probably belonged to a wider groups of Iranian tribes who lived east of Parthia proper, and there is no evidence that all the kings who assumed the title "Gondophares", which means ”Holder of Glory”, were even related.

Mitton Hoard: The Mitton Hoard is a hoard of silver coins found near Clitheroe in Lancashire, England, in 2006 or 2009.  The hoard is now in Clitheroe Castle Museum.  The documented treasure consisted of 11 silver coins or parts of coins.

Cunetio Hoard: The Cunetio Hoard, also known as the Mildenhall Hoard, is the largest hoard of Roman coins found in Britain.  It was discovered in 1978 at the site of the Roman town of Cunetio, near modern-day Mildenhall, Wiltshire, and consisted of 54,951 low value coins.  The coins were contained in a large pot and a lead container.  The coins are now in the British Museum and the pot is on display at the Wiltshire Museum in Devizes.

St Albans Hoard: The St Albans Hoard is a large hoard of late Roman gold coins found by a metal detectorist in a field near St Albans, Hertfordshire, England in 2012.  It is believed to be one of the largest hoards of Roman gold coins ever found in Britain.  The hoard consists of 159 solidi dating from the last decades of the fourth century AD, near the end of the Roman occupation of Britain.  After about 408, new Roman coins ceased to circulate in Britain, causing the collapse of the monetary economy and of mass-production industry.

Frome Hoard: The Frome Hoard is a hoard of 52,503 Roman coins found in April 2010 by metal detectorist Dave Crisp near Frome in Somerset, England.  The coins were contained in a ceramic pot 45 cm in diameter, and date from AD 253 to 305.  Most of the coins are made from debased silver or bronze.  The hoard is one of the largest ever found in Britain, and is also important as it contains the largest group ever found of coins issued during the reign of Carausius, who ruled Britain independently from 286 to 293 and was the first Roman Emperor to strike coins in Britain.  The Museum of Somerset in Taunton, using a grant from the National Heritage Memorial Fund (NHMF), acquired the hoard in 2011 for a value of £320,250.

Tregwynt Hoard: The Tregwynt Hoard is a mid-17th century hoard of coins found at Tregwynt Mansion near Fishguard in Pembrokeshire, Wales, in 1996.  The hoard is now in National Museum Wales.
