About 25mm. Roberts-8941; Boudeau-1641. A solid example from this iconic issue of Metz. Thierry V was responsible for the vast improvement in the quality of coins issued from the Metz mint. Well-designed and consistently well-executed, this issue is a noteworthy product of high Middle Ages coinage. This example offers typical medium gray toning and golden luster in the protected areas of the peripheral legends. A slight flan flaw is noted at the two o'clock position for completeness.
