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.
Vietnamese cash (Vietnamese: "văn" ; Hán tự: 文; French: "Sapèque") is a cast round coin with a square hole that circulated in Vietnam from the Đinh dynasty in 968 until the Nguyễn dynasty in 1945.
 The same type of currency circulated in China, Japan, Korea, and Ryūkyū for centuries.
 Though the majority of Vietnamese cash coins throughout history were copper coins, lead, iron (from 1528) and zinc (from 1740) coins also circulated alongside them often at fluctuating rates (with 1 copper cash being worth 10 zinc cash in 1882).
 The reason why coins made from metals of lower intrinsic value were introduced was because of various superstitions involving Vietnamese people burying cash coins, as the problem of people burying cash coins became too much for the government as almost all coins issued by government mints tended to be burried mere months after they had entered circulation, the Vietnamese government began issuing coins made from an alloy of zinc, lead, and tin.
 As these cash coins tended to be very fragile they would decompose faster if burried which caused the Vietnamese people to stop burying their coins.
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.
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.
Malta since its independence in 1964 from the United Kingdom it has issued several commemorative coins denominated in the Maltese Lira.
 In 1972, as soon as the Maltese placed aside their former colonial’s currency, the British pound and adopted the Maltese lira, Malta issued the first commemorative coin denominated in the Maltese lira.
 The Jean De La Valette commemorative coins issued in 2007 were the last Maltese commemorative coins to be denominated in the Maltese lira as Malta joined the eurozone on 1 January 2008.
 Most of the coins issued by Malta are made up of gold or silver and sometimes of Copper and Nickel alloys.
The Upchurch Hoard was a pot containing thirty-seven Roman sestertii dating from the late 1st century to the second half of the 2nd century AD found near the village of Upchurch, Kent, England, in 1950.
The sestertius (plural sestertii), or sesterce (plural sesterces), was an ancient Roman coin.
 During the Roman Republic it was a small, silver coin issued only on rare occasions.
 During the Roman Empire it was a large brass coin.
The Laeaeans ( ; Ancient Greek: Λαιαῖοι ) were a Paeonian tribe who in the 4th century BC lived adjacent to the Agrianes, another Paeonian tribe, along the upper course of the Strymon river, at the western edge of Thrace.
 They were not incorporated into the Odrysian state or the Paeonian state, remaining an independent tribe outside the borders of those kingdoms.
 According to Thucydides, the Laeaeans, along with the Agrianes, the Thracian Dii, and other tribes, joined Sitalkes in his unsuccessful campaign against Perdiccas II of Macedon.
 The coins issued by the Laeaeans are judged to be of crude workmanship, and seem to be imitations of finer minted coins issued by other neighboring Paeonian tribes such as the Derrones.
 A typical coin bears the inscription LAIAI ("Laeaeans") on the obverse, and a Pegasus in a double linear square on the reverse.
 It is unclear whether or not the Laeaeans were conquered by Philip II or Alexander the Great, although their neighbors are recorded by historians such as Arrian as client kings.
The Bredon Hill Hoard (also known as the Bredon Hill Roman Coin Hoard) is a hoard of 3,784 debased silver Roman coins discovered in June 2011 by two metal detectorists at Woollas Hall Farm on Bredon Hill in Worcestershire, approximately 400 metres north of Kemerton Camp, an Iron Age hill fort.
 The coins were found in a clay pot that had been buried around the middle of the 4th century in a Roman villa, identified by the subsequent archaeological excavation.
 The coins include the reigns of sixteen different emperors during the mid to late 3rd century, and are the largest hoard of Roman coins to have been discovered in Worcestershire to date.
