SoundOne ounce bullion bar.
I purchased this bar for spurious reasons in the early 1990s from a coin dealer near Berkeley, California. I think I paid about $500 for it, and now it's worth about $550, but in the meantime it's been worth more than double that, because of the price spike caused by catalytic converters in cars. I never noticed between then and now how much the price had gone up and back down.
In April 2002 I had Brian Knox jewelers in Champaign, Illinois weld a 90%Pt/10%Ir alloy loop onto the back of it, so it could be locked down to the table with a length of stainless steel cable.
