1/4 Uninscribed Celtic gold stater 1.43g, 12.98mm
'Yes, this is interesting. It's an uninscribed quarter stater, traditionally attributed to the Atrebates (in the South Thames) but almost certainly a North Thames issue. We have records of about 25 of them, and without exception they've come from the North Thames area: it was previously attributed to the Atrebates because of the style, which resembles their uninscribed quarter staters with a wreath on the obverse. The date of this quarter would be around c. 45 BC, I would estimate, so like the Whaddon Chase it could be just a little earlier than the Addedomaros coins. It is catalogued in Van Arsdell as VA 260-1, but not only wrongly as Atrebates but also listed as silver. Many of the surviving examples are struck from the same pair of dies, which develop some fairly major flaws, especially on the reverse; the lack of many dies suggests this wasn't a very big issue, in comparison to the Addedomaros spiral for example.
If I remember rightly there are one or two examples of this type in the huge East Leicestershire hoards which came up about 3 years ago, but mostly they're Essex/Suffolk area. This'll be CCI 05.0683'.
