The ring test is a legitimate fast filter — and nothing more. Treat it like the magnet: it can condemn, but it can never acquit.
The procedure
Balance the coin on a fingertip and tap it with another coin. Genuine silver pings with a clear, sustained ring. Base-metal fakes thud.
The limits
- It takes practice to hear reliably — train your ear on known-genuine coins first.
- Plated fakes can ring deceptively well.
- It must never substitute for the scale.
One hard rule
Do not do this with valuable graded coins. Tapping a slabbed coin risks the holder and the grade — and the test tells you nothing a cert number cannot.
A photograph can inform a decision, but it cannot authenticate or certify a coin.
