Abstract
A lead medal attributed to Antonio Averlino known as Filarete, with a portrait of Caesar, is preserved in the Gabinetto Numismatico of the Museo Civico Correr of Venice. This unicum presents oxidation coatings on both sides, so it was included in a restoration project of the Foundation of the Venetian Civic Museums. Through the acquisition of the object with high resolution scanning it is possible characterize the changes caused by oxidation coating, identify the particular style and mapping at micrometer scale the areas of degradation. For this purpose, two different laser scanning instruments are used in order to compare different resolution and accuracy and to produce a multi resolution model. The medallion was also replicated using rapid prototyping with ZPrinter 450 machine.
