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.
From 1986 to 1988, the monthly average New York dealers price of rhodium ranged from $1,150 to $1,300 per ounce. In early 1989, the announcement of problems at South Africaâs Rustenburg Platinum precious metals refinery caused the price to jump to more than $2,000 per ounce. To convert to dollars per kilogram, multiply by 32.1507.
