Copper Price Per Troy Ounce
Copper is traditionally quoted per pound (in the U.S.) or per metric tonne (internationally), but many precious metals investors and bullion buyers prefer the per-troy-ounce measurement used for gold, silver, and platinum. This page converts the live copper spot price to troy ounces for easy comparison with other metals. One troy ounce of copper weighs 31.1035 grams, approximately 0.0686 pounds, so the per-ounce price is roughly 6.86% of the per-pound price.
Copper bullion coins and rounds have become increasingly popular among collectors and stackers who value the metal's industrial importance and affordability. Well-known copper bullion products include one-ounce copper rounds in various designs, one-pound copper bars, and novelty copper coins.
Unlike gold and silver bullion, copper products are not purchased as serious financial investments due to the metal's low per-ounce value and the high premiums charged relative to melt value. A one-ounce copper round that costs $1-3 at retail contains only $0.25-0.35 worth of copper at spot price, representing a premium of 300-800% over melt value.
Copper has a long history in the numismatic world. Pre-1982 U.S. pennies are 95% copper and contain approximately 2.95 grams of copper each, making them worth more than their face value when copper prices are high. Some collectors specifically save pre-1982 pennies for their copper content.
The conversion from per-pound to per-ounce pricing is straightforward: divide the COMEX per-pound price by 14.5833 (the number of troy ounces in one avoirdupois pound). This conversion allows copper enthusiasts to compare their holdings directly against gold, silver, platinum, and palladium using the same unit of measurement that dominates precious metals markets.
