The
reverse (image at left) is typical of the way the figure of
Spes breaks down in some of the more degraded barbarous radiates.
Sutherland (
Coinage and Currency in Roman Britain, p. 146) describes it as "elaboration of the tunic-top of the drapery, with its flowing outlines, into a
stylized double-curve, through the middle of which passes a kind of axial line". Your coin is similar to
his example on plate X, #6. The image should be rotated about
180 degrees so that the T-shape would represent the
head, the narrower curves the breasts, the wider curves the hips, and the psi-shape the raised skirt. The
legend is most likely a semi-literate attempt at
SPES AVG, the resemblance to "
Divo" being only a coincidence.
The
obverse bust on
Spes types usually derives from
Tetricus I, but these being copies of copies of copies, the engraver may not have known exactly what or who he was really copying.
If from
Gaul, your coin would date to a point sometime after the issue of the prototype and up to the reform of
Aurelian c. 275; if from
Britain, where the "epidemic" of barbarous radiates persisted a
bit longer, perhaps as late as the early 280s.
