The Ardagh Hoard, best known for the Ardagh Chalice, is a hoard of metalwork from the 8th and 9th centuries. Found in 1868 by two young local boys, Jim Quin and Paddy Flanagan, it is now on display in the National Museum of Ireland in Dublin. It consists of the chalice, a much plainer stemmed cup in copper-alloy, and four brooches — three elaborate pseudo-penannular ones, and one a true pennanular brooch of the thistle type; this is the latest object in the hoard, and suggests it may have been deposited around 900 AD.
The Breadalbane Brooch is a luxurious Celtic penannular brooch probably made in Ireland, but later altered and then found in Scotland. Probably dating to the 8th century, with 9th-century alterations, it is an intricately designed, silver-gilt dress fastener that is closely related to a select group of brooches that were produced in Ireland and Britain during the 'golden age' of late Celtic art. The brooch has been in the British Museum since 1919, and is normally on display.

The Hunterston Brooch is a highly important Celtic brooch of "pseudo-penannular" type found near Hunterston, North Ayrshire, Scotland, in either, according to one account, 1826 by two men from West Kilbride, who were digging drains at the foot of Goldenberry Hill, or in 1830. It is now in the National Museum of Scotland, Edinburgh. Made within a few decades of 700 AD, the Hunterston Brooch is cast in silver, gilt, and set with pieces of amber, and decorated with interlaced animal bodies in gold filigree. The diameter of the ring is 12.2 cm, and in its centre there is a cross and a golden glory representing the Risen Christ, surrounded by tiny bird heads. The pin, which is broken, can travel freely around the ring as far as the terminals, which was necessary for fastening; it is now 13.1 cm long, but was probably originally 15 cm or more.

The Kilmainham Brooch is a late 8th or early 9th century Celtic brooch of the "penannular" type. With a diameter of 9.67cm, it is a relatively large example, and is made from silver, gold, glass, with filigree and interlace decorations. Like other high quality brooches of its class, it was probably intended to fasten copes and other vestments rather than for everyday wear, as its precious metal content would have made it a status symbol for its owner; less expensive Viking-style brooches were typically worn in pairs on in women's clothing.
The Londesborough Brooch is a Celtic pseudo-penannular brooch from Ireland. Dating from the late eighth or early ninth century, it is a particularly elaborate example of a dress fastener dated to Ireland's artistic golden age, when objects such as the Tara Brooch and Ardagh Chalice were produced. Since 1888, it has been part of the British Museum's collection.

The Penrith Hoard is a dispersed hoard of 10th century silver penannular brooches found at Flusco Pike, Newbiggin Moor, near Penrith in Cumbria, and now in the British Museum in London. The largest "thistle brooch" was discovered in 1785 and another in 1830, with the bulk of items being recovered in two groups close to each other by archaeologists in 1989. Whether all the finds made close to each other were originally deposited at the same time remains uncertain, but it is thought likely that at least the brooches were. The brooches are thought to have been deposited in about 930.

The Roscrea brooch is a 9th-century Celtic brooch of the pseudo-penannular type, found at or near Roscrea, County Tipperary, Ireland, before 1829. It is made from cast silver, and decorated with zoomorphic patterns of open-jawed animals and gilded gold filigree, and is 9.5 cm in height and 8.3 cm wide. The silver is of an unusually high quality for Irish metalwork of the period, indicating that its craftsmen were both trading materials with settled Vikings, who had first, traumatically, invaded the island in the preceding century, and had absorbed elements of the Scandinavian's imagery and metalwork techniques.

The St Ninian's Isle Treasure, found on St Ninian's Isle, Scotland in 1958 is the best example of surviving silver metalwork from the Early Medieval period in Scotland. The 28-piece hoard includes various silver metalwork items, including twelve pennanular brooches. The treasure is now in the National Museum of Scotland.

The Tara Brooch is a Celtic brooch of the pseudo-penannular type, made c. 710 to 750 AD. It was found in Ireland in 1850, but, despite its name, not at Tara but likely near Bettystown on the coast of County Meath. The name by which the brooch became known was attached to it by the jeweller who purchased it, as a marketing ploy for the copies they made. The brooch was exhibited internationally and was one of the artifacts that fuelled the Celtic Revival in the mid-19th century. It is in the collection of the National Museum of Ireland in Dublin.
