Roman Empire, Probus, Antoninianus Roma

Note: RIC lists these coins with R-><-A (R thunderbolt A), RჲΓ (R wreath Gamma), RჲΔ (R wreath Delta), omitting R thunderbolt Delta.
R thunderbolt A is most certainly a misreading of Δ for A, since hundreds of such coins have been attested from hoards as being from officina four. Meanwhile, I have never come across a specimen with Romae Aeter from officna one (R thunderbolt A). Officina 'A' in the last emmissions before the coded eqviti series officina A only struck Victoria Germ reverse, not Romae Aeter reverse. Thus, rather than a variant, one can catalogue coins with R-><-Δ as either RIC 183, ignoring RIC's mistake, or as RIC 183 corr. - above observation courtesy of Grzegorz Kryszczuk.
