Technical Observations: The patina is dark green with spots of underlying red. Areas of the surface corrosion have been lost. Most of the surface is well preserved.
There are no hammer marks or cold-working marks, and it is likely the pin was cast from a model formed directly in wax. The hole is oval with rounded edges, and there is no evidence of drilling. It may have been formed in the wax model.
