BRUTTIUM. Kroton. Circa 375-350 BC. Trihemitetartemorion (Silver, 7.5 mm, 0.25 g). Ϙ Tripod with legs ending in lions' paws, with three high rings on the bowl and a thin neck. Rev. Three Τs in a triangular arrangement, with a pellet at the center and one between each. Apparently unpublished save for its auction appearance, but see Attianese 177 for a slightly similar piece. Extremely rare. Clear and well-centered. Rough surfaces and a flan crack, otherwise, very fine.
From the Dr. Paul Peter Urone Collection, ex Classical Numismatic Group MBS 64, 24 September 2003, 38.
When this extraordinary coin appeared in 2003 it was sold as an obol, which, given the denomination clearly indicated by the three Τs on the reverse, was quite perverse! Since the weight makes it clear that it cannot be three tetartemoria (1/4 obols) or a 3/4 obol piece, it has to be three half-quarters, or three eighths!
