With 85 million iPhones having been sold since 2007, consumers are sitting on $154,700,000 worth of gold or  85,000 ounces of gold. That is because, in each one of those iPhones, there is approximately 0.034 grams of gold, according to the US Geological Survey. That is approximately $1.82 of gold. In each phone, there are also 16 grams of copper, worth about 12 cents, meaning about $10 million in that base metal overall. With 0.35 grams of silver (29,750,000 ounces), worth 36 cents a pop (30,600,000 altogether), and 0.00034 grams of platinum, approximately 2 cents.

While not an overwhelming amount of metals being sat on in the US, it is still a considerable amount of metals that will only increase over time as Apple continues to make iPhones. There is a chance, to be sure, that the development of new iPhones slows as the models year-to-year change less than the year prior.
