For those new to the subject: Antioch at this period used a mintmark consisting of AN + the Greek numeral for one of their 15 workshops. ANH would be shop 8. I is the Greek numeral for 10 so shops 11 through 15 had an extra letter. Below is ANBI which is AN for the city + B for 2 + I for 10 or shop 12. RIC catalog assumes you understand things like this and do not assign a different catalog number for ANA, ANEI or anything in between.
The answer is yes, from the Aquileia mint, but they are very rare. I collected early Christian symbols on Roman coins for over thirty years before I even noticed its existence. It is much like Doug's forth coin above, but with a chi-rho where his has a wreath in the middle. The chi-rho in the middle of the field of an otherwise common FTR solider-spearing-fallen-horseman of Constantius Gallus. Fortunately, the chi-rho is reasonably strong. RIC Aquileia 115.
