The symbolism behind the imagery on this silver round is explained on the website of the Golden State Mint by the following:
The Trivium has always been vital to the Silver Shield message as a way of using Grammar, Logic and Rhetoric to find not only truth, but the right path to follow. The Trivium Girls is the physical embodiment of this intangible concept.
Lady Grammar, on the left, listens to all and follows none as she searches for truth.
Lady Logic, in the middle, uses her mind to process this information that is to free her from the mental and physical shackles.
Lady Rhetoric, on the right, is totally free and heralds a new consciousness to the world free of fear and ignorance. [1]
The reverse (back) of the round features the Silver Shield symbol, superimposed by a flaming sword and flames near the rim, and is stamped "1 TROY OUNCE .999 PURE AG," where "AG" is the chemical symbol for Silver (from the Latin Argentum).
The edge of the round is reeded, for an attractive, finished look.
As is the case with many items in my collection, I wanted this particular design because of the feminine imagery and symbolism on it. It is certainly a beautiful item and I am thrilled with the Trivium Girls!
