A very nicely preserved and rare in terms of variety denarius of the "reliquary" type.
Characterized both by the unusual and erroneous arrangement of the ruler's name notation (B-O-AL-E-S-L-A-VV), as well as by an interesting sign above the ruler's head: a sword!
On the reverse, the saint's name clockwise (S ADALBERIVS).
Silver, diameter 16 mm, weight 0.52 g.
