Ghana's Mint has produced a series of wildlife-themed silver rounds under the "Creatures of the Night" program, with the salamander entry joining issues like the scorpion and the spider. The obsidian insert — volcanic glass with a Mohs hardness around 5.5 — is sourced and set separately from the casting process, requiring individual placement rather than a standard coin press operation.
