John Williams - Gold to Prevail as System Falls into Disorder : The earlier all-time high of $850.00 of January 21, 1980 would be $2,472 per troy ounce, based on November 2011 CPI-U-adjusted dollars, $8,702 per troy ounce based on SGS-Alternate-CPI-adjusted dollars. In like manner, the all-time high price for silver in January 1980 of $49.45 per troy ounce, although approached earlier this year, still has not been hit since 1980, including in terms of inflation-adjusted dollars. Based on November 2011 CPI-U inflation, the 1980 silver price peak would be $144 per troy ounce and would be $506 per troy ounce in terms of SGS-Alternate-CPI-adjusted dollars.”
