It's this Constantine? http://coinvac.crabdance.com/810259
No, Ras. It's supposed to be a
Probus aureus as cited here: "Calicó -,
cf. 4154a =
NFA XXV, 29 November 1990, 461 (
bust right). 6.71g, 21mm, 11h."
Citation is from an upcoming sale, so I'm not going to link it here.

But I found the cited coin. Many thanks to the coinvac and the dancing crabs!
Extraordinarily useful database, there. Thanks again.
