Pearl-diademed, draped, and cuirassed bust left / Basiliscus monogram within wreath; [K]OC. 10mm, 0.75 grams. Constantinople mint. RIC X 1014 var (bust right); LRBC 2284 var (bust right).

Very rare, excellent quality for this late issue.

Very interesting example, with the bust left (and not right) - this variety (with the bust left) is not in RIC. Large flan for these, with a nearly complete monogram. 

From an old US collection.
