Constantius London Nummus from a "Caen hoard" ?

[JulianIX]

The original ticket on this Constantius said 'ex Caen hoard'. Searching online including University Oxford database I can't seem to find anything with the right dates nearer than Treasure of Saint-Germain-de-Varreville - maybe 100km from Caen. 
There's a Caen hoard mentioned by Ashmolean but last dates is Tetricus 270s whereas this Constantius coin is 296 struck at London mint.

[Hugh Cloke]

The term 'Caen hoard' was used by Ron Bude to refer to a large hoard of nummi marketed by the firm of Freeman and Sear.  The hoard was reported by F&S to have been found in France but the hoard was never catalogued and F&S was vague about the location of its discovery.

This particular coin is recorded in LMCC II on page 322, footnote 60, example 3.
