The work has come down to us intact, without presenting lesions or fissures, and in a fair state of preservation. All surfaces were covered by a thick layer of greasy dust and a widespread blackening that prevented the perception of the various metals.
The gilding was so tarnished and locally blackened that the variety of gold alloys used was not perceptible. The decorated surface of the shield presented a thick layer of waxes that were by then blackened, oxidized, and crystallized. The areas most affected by severe blackening were the silver decorations, which were completely darkened by compact sulfurations that had taken on the same color as the patinated bronze background.
Locally, formations of green copper oxides were noticeable, and there was no evidence of active bronze corrosion attacks. The surfaces of the work show no deformation or mechanical damage, with the exception of Garibaldi's head, on whose surface slight scratches and abrasions are visible.
