Cut sheet.
This is a small strip cut from a piece of "scrap" 1mm sheet. The price of rhodium has shown alarming volatility in recent years. For most of the time it sells(in today's money) for around $500 per troy ounce which is just over 31g. However for a brief period in 1990, with rising demand for making catalytic converters that could reduce emissions of nitrogen oxides, the price spiked to $7,200 per troy ounce. At that price a kilogram of rhodium cost almost quarter of a million dollars! The small piece here was worth $1,000.
