Summary

Description
English: The information depicted is presented as is. The creator of this graphic, Alexander Zhikun He, neither endorses nor advocates any investment in (or out) of gold. Interpret at own risk.

Note: $20.67 was officially convertible into a troy ounce of gold from Mar 1900 until Jan 1934, then $35 per troy until Aug 1971 ("en:Nixon Shock"). Rather than use the official values, I opted instead to use historical London prices and dollar-pound exchange rates—partly to make the chart a bit more "interesting", and also to reflect natural market inefficiencies (i.e, how a purchaser may pay a slight premium in the market to forgo the inconvenience of travel to a dollar-gold redemption location.)

This chart uses yearly points until April 1968, and daily points thereafter. Constant prices and percentile lines are based on a daily interpolated Consumer Price Index (CPI), adjusted to the month in the chart legend. Since the US Dept. of Labor only provides monthly CPI values, I interpolated the daily CPI with the following formula: Daily CPI adjustment = (current month-end CPI / previous month-end CPI) ^ (1 / # trading days in month).

I will not be posting the data set since it may be extract from the SVG file's vectors. (In fact, the SVG contains the data set twice, once to draw the plot lines and again to draw the area under the line. As such, adding the set would result in a description page just under half that of the full-sized SVG—i.e. over 700kb as of August 2014.) Intended frequency of updates is 2-4 times per year, though may be as often as once a month during volatile periods. Feel free to poke me at my talk page if prices have drifted more than 15 percent.
