Although square pennies are patterns that were never destined for circulation, the occasional lower-grade square penny does indeed appear on the market. Whether the specimen was a test coin used to measure wearing patterns, or a pocket piece kept by some mint official, a worn square penny is often the only opportunity for the collector of limited means to acquire an important Australian rarity at a discounted price. This is one of those times. The coin on offer here is evenly worn, with rub on the high points of George V’s moustache and the kookaburra’s breast. There is also a minor edge knock on the obverse at 1 o’clock. In any case, the coin is presentable and attractive, and would suit an Australian rarities type set or even a penny collection. Well priced at this level, and probably one of the most affordable square pennies available on the market in recent times. Professional Coin Grading Service is the global leader in coin authentication and grading. With over 60 million coins graded and counting, PCGS is trusted by collectors, dealers, and investors to certify authenticity, protect value, and elevate market confidence. This is a direct conversion of the 70-point PCGS grade to a 10-point scale, intended to present the grade in a more intuitive format for newer collectors. It is not our personal opinion or an attempt at regrading the coin to a different standard.
