Lead Filled 100 Ounce Silver Bars
Lead-filled silver bars apparently first started appearing in the early 1980s, as the price of silver skyrocketed. The bars started off as real 100 ounce silver bars. Someone then removed much of the silver, and replaced it with another metal, probably either lead or a lead-tin alloy with the same weight as silver. Unfortunately, there is little credible information available (for example, some people claim that they have only heard of this happening with Engelhard bars, but that may be because the 2 pictures of such bars happened to be Engelhard bars).

Lead 100 Ounce Silver Bars
In Late September, 2010 we received our first of several reports of some suspicious Engelhard 100oz silver bars. They were underweight, and it at first appeared that they were real Engelhard bars that were shaved (where someone wouldcut off a small amount from the sides of the bar).
