The Slide, is the simplest and fastest way to detect fake silver. The testing mechanism uses a strong magnet, fake silver coins will slide smoothly with no resistance. However, real silver coins slide slowly as the neodymium magnets repel the silver with some resistance.
The Slide does not have any toxic chemicals and can read through numismatic cases and plastic capsules. It is recommended for a quick and easy screening process. Please be reminded that no single testing tool should be relied upon solely to authenticate silver bullion.
