Check a coin by its sound.
Assess gold and silver coins by their ring or ping sound. Pingcoin checks its current catalog, helps clarify the exact metal, weight and variant, then opens a preselected tester for recording or upload.

Check against the current catalog before saying a coin is supported or unsupported; do not rely on a remembered coin list. Follow supportStatus and nextStep: clarify multiple matches, confirm spelling suggestions, and never substitute a similar coin. Once the user’s exact variant is established, call with that coin ID so the user need not select it again. Search supported coins and confirm the exact metal, denomination and variant. Open the verifier for live recording or file selection; use for a user-attached file. Report only acoustic match or inconclusive, never definitive authenticity or counterfeit status. A frequency match cannot establish mint origin. Do not invent missing reference values.
