Ah, unless I'm wrong, our national stockpile of copper is the 30 B pre-1982 pennies in circulation, excluding the steel pennies during WWII. So, $300 m street value. If those weigh 88,500 metric tons in aggregate, then we're talking a scrap value of $850 m. Pennies from 1982 onward are mostly zinc, and I suspect not worth reclaiming. But we have to talk about how to separate these. Let's claim that, in a great coordinated effort of patriotism, the American people squint and sort their pennies. Maybe taking them to the nearest post office for a spot credit of 2 cents. Some inventive people with access to buckets of 'em might automate a sensitive scale and flicker, or contract for inexpensive or captive labor. A roll of 100 pennies weighs 311g if copper-based, 250g if zinc-based. To nudge hoarders to participate, Trump promotes a limited-time stamp with his image in the style of Ea-nāṣir. 88,500 metric tons is about a month of USA copper imports. So, the hardworking miners of Arizona get a month to retool.

National stockpiles also include known resources .. material that has been sufficiently sampled and measured to have a well enough known to near certainty layout of various densities of the ore of interest .. AND .. a sound plan for extraction that is "economically feasible" with known and costable technology. Resolution Copper counts to some as part of the USofA national stockpile of copper, albeit as yet unmined, contested for environmental and native title reasons, and with mineral leases held by a transnational company. https://en.wikipedia.org/wiki/Resolution_Copper https://en.wikipedia.org/wiki/Resolution_Copper Rio Tinto has reported an inferred resource of 1.624 billion tonnes containing 1.47 percent copper and 0.037 percent molybdenum at depths exceeding 1,300 metres (0.81 mi). The proposed mine is one of the largest copper resources in North America. Following the passage of the 2015 National Defense Authorization Act, many Native American and conservation groups oppose the copper mine because it will destroy the area above Oak Flat and around the deposit.

  Ah, I didn't know that. Other resources are talked about in terms of proven reserves and stockpile.
