Among the early highlights is Lot 3, a drachm of Celtic origin. This remarkable silver piece is an outstanding example of Central European Celtic coinage from the late La Tène period, likely produced by a Boii or Boii-adjacent community active in the middle Danube basin during the 1st century BC. Though rooted in the Macedonian numismatic tradition of Philip II, its execution is distinctly Celtic, abstract, symbolic, and technically assured.
No identical obverse-reverse die combination or symbol configuration is known, and the coin's pristine preservation, fine toning, and balanced design make it a significant addition to the typology of late La Tène silver. Estimated at £2,000.
From the Roman Empire, Lot 270takes centre stage: a Constantine I "the Great" Medallion (1.5 Solidi). Perfectly struck and centred, with crisp detail and rich reddish-gold toning, this gold medallion is of the utmost rarity, unrecorded in standard references and seemingly one of only two known examples.
Struck shortly after Constantine's final war against Licinius in AD 324, it depicts an emperor on the threshold of absolute rule. With Licinius' defeat and surrender, the Roman world once again stood united under a single Augustus. Gold multiples such as this were struck for ceremony rather than commerce, rewarding loyalty and asserting imperial legitimacy. This medallion exemplifies that exclusive tradition of coinage as political theatre, revealing Constantine as both victor and architect of a new imperial order. Estimate: £70,000.
Another major highlight is Lot 360, a fabled Fatimid AV Dinar of al-Mu?izz li-Din Allah, struck in Makka (Mecca) a coin of the utmost rarity, with only three specimens recorded and the finest ever to appear at auction. Struck in AH 363 (AD 973/4), it represents the first Fatimid gold issue from Makka and ranks among the most coveted coins of the Islamic world.
Struck soon after the Fatimids secured Egypt in AH 358 (AD 969) and extended their authority eastward, the coin commemorates the moment their sovereignty was recognised in the Friday khutba of both Makka and Madina, the clearest sign of sovereign legitimacy in the Islamic tradition. Estimate: £80,000.
