How much did Alessandro Volta's first battery cost?

Alessandro Volta's first battery, known as the voltaic pile, was not commercially sold, so it didn't have a specific price tag. Instead, it was a scientific invention created in 1800 to demonstrate the generation of electricity through chemical reactions. The materials used in the voltaic pile, such as zinc, copper, and cardboard soaked in saltwater, were relatively inexpensive at the time. However, since it was primarily a demonstration of scientific principles, its cost isn't easily quantified in terms of a market price.
