A fully tarnished, shiny black silver artefact was tried out as a detector in place of the germanium transistor in my series-tuned, shunt-fed crystal radio.

i have used gilette shaving blades, lead melted with aluminum, and also some iron.
not all gave good performances but all were able to perform as a PN junction for rectification,detection.
depends on your ground and the quality of your crystal headphones.
