1975 1 Oz World Trade International Round BU

Generic rounds minted in the mid 1970s often emphasized the global value of silver and its potential as a trade unit. Although the mint for this round is unknown, the reverse is identical to rounds attributed to California Crown Mint a few years later. This suggests a link between the company that produced the initial rounds and California Crown Mint. The mintage for this round is unknown, but the round is uncommonly encountered today.

Obverse: The central feature on the obverse is a globe centered on North and South America. The phrase "WORLD TRADE" is inscribed above the globe, while the composition of ".999 FINE SILVER" can be found below. The phrase "ONE SILVER" in different languages (German, Japanese, Chinese, English, French, and Spanish) encircles the globe. The date "1975" is found at the bottom. 

Reverse: The central feature on the reverse is the balance scales, a common motif found on many trade unit silver rounds. Sprigs of ivy flank the scales to either side. The inscription located at the top, "THE INTERNATIONAL", is matched by "SILVER TRADE UNIT", which is centered at the bottom. The content of "ONE TROY OUNCE" is inscribed below the top inscription, and the purity of ".999 FINE" is inscribed immediately above the scales. An additional weight designation of  "31.1 GRAMS" is located underneath the trade scales.
