>Some 60% of actively circulating coins, or as much as $14 billion, sit in coin jars, according to the Federal Reserve.
Good information.
100% / 60% = 1.6666667
1.6666667 x 14B = 23.3333B
If all those coins were converted to constitutional coinage, it would take:
$23,333,333,333 x .723 grams per dollar = 16,870,000,000 grams, or 542 million ounces
With current silver prices just over $1 per gram, the US could have constitutional coinage again for $17 Billion dollars.
