a very attractive specimen, with only the slightest rubbing on emu's feathers, the highest areas of the kangaroo's body (rev), and bit more on Lizzie's shoulder (obv).
Full luster, fields reasonably clean.
Better struck than most examples, with fully struck up details on Lizzie's ear.

These coins were made from
.500 silver quaternary alloy, the other metals being copper 40%, zinc 5% and nickel 5% - (to harden the alloy). The blanks were blanched in acid (to enrich the silver in the surface), then rinsed before being rimmed into planchets.
Generally, quaternary alloy coins with enriched silver surface showed signs of darkening as they developed wear in circulation, exposing the un enriched alloy underneath.
This coin shown none of that sort of problem.
