Usually, silver stackers buy pea-sized neodymium magnets and then place them on the silver bar or coin. If it's real, when they tilt or tilt the silver, the magnet will slide smoothly. This is because real silver has a very weak magnetic effect. A relatively easy and fun way to test your silver ingots and coins is to place an ice cube on them.
Additionally, if you are looking to diversify your retirement savings, you may want to consider rolling over your 401k to a Gold IRA Account. Even at room temperature, authentic silver products will melt ice at an extremely fast rate. For best results, try casting a second cube into another type of metal, such as copper, steel or aluminum.
