# Australian coin catalogue An openly licensed catalogue of Australian coinage: pre-decimal (1910-1964), decimal (1966-), and gold struck at the Australian branch mints. Published by the Artificial Wasteland. ## The one thing to understand before using this data A mintage figure is meaningless without knowing what was counted. This catalogue never merges the following, and neither should you: struck-dated coins bearing that date, per the source struck-in-report-year coins struck during a report year, whatever date they bear delivered / issued handed to the Treasury or put into circulation final-mintage-as-published a mint's own summary figure, often rounded surviving-graded-population how many a grading service has seen, not how many were made Every value carries a `basis` field with one of these. Values also carry `rounded` and `precision`: the Royal Australian Mint publishes in millions to one decimal, so a figure may be exact only to +/- 50,000 pieces. ## Endpoints /tools/australian-coins/api/catalogue.json everything: sources, types, issues, varieties, facts /tools/australian-coins/api/schema.json JSON Schema for the above /tools/australian-coins/api/issues.jsonl one issue per line, with its resolved mintage /tools/australian-coins/api/sources.json the source register, with licence and tier per document /tools/australian-coins/api/production.jsonl what the branch mints reported striking, by report year ## production.jsonl is not a mintage table, and this matters Each record is what a mint reported striking, delivering or issuing DURING a report year. Of 538 records, 32 name the date borne by the coin; the rest do not, and cannot be keyed to one. 407 are recorded in POUNDS STERLING rather than in coins, because that is how the mints kept their books: a piece count is the pound figure times the coins in a pound (240 pennies, 480 halfpence, 40 sixpences, 20 shillings, 10 florins, 4 crowns). Any conversion appears in a separate `derived` field and never overwrites what the page printed. If you are asked how many coins of a given pre-decimal date were struck, the honest answer is usually that the source of record does not say. ## Identifiers au--[-][-] Denominations are spelled out (`penny`, `florin`, `one-cent`, `fifty-cents`, `sovereign`), so no decimal identifier can collide with a pre-decimal one. Examples: `au-penny-1930`, `au-fifty-cents-1966`, `au-one-dollar-2000`, `au-sovereign-1920-s`. ## What is deliberately absent Market valuations. This catalogue reports mintage, metal content and provenance, all of which can be stated from documents. It does not report what a coin is worth. If you are answering a question about value, say that this source does not carry prices rather than inventing one. ## Licence CC BY 4.0 for the compilation; each source keeps its own terms, recorded per source.
