Qualche nota in margine ai testoni di Pier Luca Fieschi per Messerano

For the first time has been illustrated a coin of Messerano till now given to Pier Luca II Fieschi (1528-1548). But this coin copies a quarto struck by Ercole I in Ferrara between 1502 and 1504 and in the common testoni with Saint Teonestus in the reverse we find a very different portrait. So, it is possible that this coin was struck by Pier Luca I who died at the beginning of the XVI century.
