Every year above opens to the documents behind its figure. 2 of 68 also have a page of their own, where there was more to say than a row can hold.

What it is made of

Not copied from a table. Each row is the standard the instrument named beside it actually prescribed, and the fine metal weight is derived from that standard rather than looked up. Where a column says "not stated", the instrument does not state it and we will not supply a number it does not carry.

In force	Standard weight	Composition	Fine metal	Diameter	The instrument

Varieties and errors

A variety is a claim about a coin, and claims differ in how well they are evidenced. The grade beside each says what kind of source stands behind it. This catalogue prints no valuations, so nothing here tells you what a variety is worth.

Variety	How you tell it apart	Evidence	Source
1966 Wavy Baseline / Wavy 2	Curve at top of 2 baseline; matching curve in wave above; thinned downstroke	scholarly a numismatic society, museum catalogue or archival study	source On genuine ‘wavy’ 20 cent coins there’s a corresponding curve in the water wave above the base line and a thinning of the downstroke of the 2. https://www.ramint.gov.au/collect/national-coin-collection/circulating-coins/twenty-cents [200] prose: “All twenty cent coins in the first issue in 1966 were produced at the Royal Mint, London.”; same page table [200]: “1966 28.2 RAM 1966 30.0 RML”
