Mr. Evans read a paper " On a Hoard of Roman Coins found near
Luton, Beds.," on the estate of John Shaw Leigh, Esq., of Luton Hoo.
The coins, which must have been nearly a thousand in number, had
been deposited in an imperfectly burnt urn composed of clay and pounded
shell», and consisted of denarii and small brass, ranging from the time
of Caracalla to that of Claudius Gothicus. Though there were upwards
of thirty coins of the latter emperor in the hoard, and though one
coin of Marius, the immediate predecessor of Tetricus, was found, yet, as
far as could be ascertained, not a single coin of Tetricus was present.
This is the more remarkable when it is considered that the dominions
of Tetricus were Gaul, Spain, and Britain, and that we learn from
Trebellius that when Claudius Gothicus was proclaimed, the accession
of Tetricus in the western part of the empire was already known in
Rome. And yet some of these coins found at Luton bear the second
year of the tribunitian power of Claudius upon them, while none of
Tetricus are found with them. The most probable manner of accounting
for this circumstance appears to be, by supposing the coins of
Claudius with TB. p. n. to have been actually struck during his first
year, especially as none of his coins bear simply TH. p., and assuming that
Tetricus did not commence striking coins immediately after he had
been proclaimed. Indeed, we learn from history that at the time of his
election Tetricus was absent, and it was only on his arrival at Bordeaux
that he was installed as emperor. Taking this view of the case, the
hoard discovered at Luton must have been deposited in the summer or
autumn of A.D. 268, or, at the latest, early in 269.
Mr. W. Allen also communicated an account of the same hoard,
giving a list of nearly a hundred coins which he had examined.
Unfortunately, a large number of the coins had been dispersed by the
labourers who found them, of which these formed a part ; those examined
by Mr. Kvans having been principally such as had been given
up to Mr. Leigh, the owner of the soil.
