We are looking for something that suggests, connotes, and/or evokes our values (see below). Also, it should be iconic, web 2.0 friendly, clean and sophisticated, and essentialized.
We are envisioning the look of watercolor or marker or something along those lines.
We included logos we like. They are all instantly recognizable and iconic (in different ways). Most give a strong gestalt response. Most give one a feeling of what the brand stands for or what its consumers aspire to (e.g. Johnnie Walker). Pizza Hut and WWF have that watercolor/marker look that is well executed, clean, simple, and friendly. Most of them are representational, though not attempts to be drawings of something (other than Johnnie Walker).
We uploaded a sketch of a logo showing a gold coin, a scales, and a ruler. These associate gold with fair and objective measurements of weight and length (gold is the means of measurement of economic value). Also, the scales have a secondary connotation and that is justice.
This sketch should not be taken too literally, though it might be possible to render a concept that uses it as a starting point.
The values of the gold standard are honesty/integrity, productivity/prosperity, justice, soundness/solidity, peace, and it just works.
