| Obverse description | The fourth portrait effigy of Queen Elizabeth II facing right, wearing the Girls of Great Britain and Ireland tiara, as designed by Ian Rank-Broadley. The sovereign's name appears in the upper legend, flanked by the issuer name and denomination, with the engraver's initials IRB truncated below the portrait. The overall composition is restrained and heraldic in character, consistent with standard Commonwealth coinage conventions of the period. |

The "Pad Printed" designation marks this as part of Perth Mint's early experimentation with inkjet-style color application directly onto the coin surface — a technique that distinguishes it from the enamel inlay and hand-painting methods used by other mints in the same period. Perth developed the process largely in-house, and adhesion consistency on early runs was a documented quality control concern.
