Bring the water to the boil but do not allow it to boil vigorously-maintain a gentle boil for one minute exactly. Remove the saucepan from the heat and allow the eggs to cool slowly in the water(this can take up to an hour). When the water is cool, remove the eggs, peel and slice in half.
See figure 2 for an example of a Baird Mint rhodium bar. The spot price of rhodium (November 2014) is at $1170.00 per Troy ounce. The 1/10 ounce bars sell for around $210.00 to $230.00. This is a much larger premium over the melt value when compared gold or platinum. The premium on the one ounce bar is around $200.00 to $250.00.
In January 1997, the rhodium price sank to $200 per ounce, its lowest level in nearly 24 years. Prices began to rise again in June, reaching a peak of $370 per ounce, as delayed shipments from Russia caused a shortage of supply.The price retreated to $300 per ounce in August but rallied to $360 at yearend, following speculative buying in the United States. To convert to dollars per kilogram, multiply by 32.1507.
