At times, the price of osmiridium is very high. In 1921, £42 10s. an ounce was being paid for it on the Tasmanian fields. The London price is said to have once touched the surprising figure of £85 an ounce.

February 1921: "The buyers of Tasmania's production of osmiridium are not quoting, and although recent sales were made on the basis of £34 per oz. for average metal, it is expected that the price will be serious reduced."

1918-1919: A 'significant' export of Osmiridium from Papua (reported in Pacific Ports Manual, 7th Ed. 1921) was presumably declared in avoirdupois ounces (hence, 5.5 lbs. avd or 80.66 Troy Ounces.) A packet of 2.5 lbs. avd is 36.46 Troy Ounces, whereby a single opportune discovery (in the rainy season, April 1919?) represented nearly half the entire Papuan export for that year.
