Rectangular Æ Solidus Weight (?) or Dedicatory Plaquette. Circa AD 507-511. Silver inlay legend: BAC AVD APV in three lines. Unpublished in the standard references, for similar examples cf. S. Benadall, Byzantine Weights, 1996, 172 (in the names of Zeno, Odovacar and Symmachus, now in the BnF, Paris); J. Forien de Rochesnard, Album des poids antiques 3, Rome et Byzance, p. 51 (in the name Albinus); NAC sale 5, 1992, 621 = NAC sale 54, 2010, 1339 (in the name Paulinvs praef. vrb.). 4.30g, 15mm.
If these are solidus weights they usually suffer the drawback of being light, perhaps due the deterioration of the bronze, and weigh between 4.28g and 3.66g. H. Dressel in 'Corpus Inscriptiones Latinorum' (CIL) 15, listed these as 'tesserae monumetorum' or dedicatory plaquettes intended to mark dedications, reconstructions or repairs to buildings on the basis that some bear the formula renovavit, which perhaps points to this conclusion.
