Current chart artwork — photographic style edits, 28 October 2026 All coin faces in the current HTML chart are AI-retouched from supplied photographs, with a common satin-metal finish and transparent background. These are adapted illustrations; they are not unchanged documentary photos. Original sources and edited images are paired in photo-style/review.html. Exact input/output paths are in photo-style/edits.json. Prompts, source files and metadata are retained in photo-style/. USD retains its original photographic note images. EUR includes Germany, France, Greece, Finland and the common denomination face. Italy was sourced but not included because the edit tool rejected its output. CNY now uses the standard chrysanthemum design. GBP uses the 2016 collector specimen of the twelve-sided design, including its cross-crosslet mintmark. Follow-up normalization: CHF denomination face matched to Helvetia brightness; four EUR national faces matched to common-face gold/silver tones; AUD portrait matched to reverse brass tone. Renderer standardizes coin diameter and removes added white outlines. Earlier edit versions are retained in photo-style/normalization/before and photo-style/chf-normalization. Current source credits (edited adaptations retain the original reuse terms): CAD and MXN: see the original source credits below; JPY both faces: TiagoLubiana, CC0, as listed below. eur-germany-photo.jpg: Renhour48 — CC0 https://commons.wikimedia.org/wiki/File:Allemagne_-_Pi%C3%A8ce_de_1_euro_2002.jpg https://creativecommons.org/publicdomain/zero/1.0/ eur-france-photo.jpg: Renhour48 — CC0 https://commons.wikimedia.org/wiki/File:France_-_Pi%C3%A8ce_de_1_euro_1999.jpg https://creativecommons.org/publicdomain/zero/1.0/ eur-italy-photo.jpg: Renhour48 — CC0 https://commons.wikimedia.org/wiki/File:Italie_-_Pi%C3%A8ce_de_1_euro_2002.jpg https://creativecommons.org/publicdomain/zero/1.0/ eur-greece-photo.jpg: Renhour48 — CC0 https://commons.wikimedia.org/wiki/File:Gr%C3%A8ce_-_pi%C3%A8ce_de_1_euro_-_2007.jpg https://creativecommons.org/publicdomain/zero/1.0/ eur-common-photo.jpg: Albertomos — CC BY-SA 4.0 https://commons.wikimedia.org/wiki/File:2002-Euro-1-Euro-d.jpg https://creativecommons.org/licenses/by-sa/4.0/ eur-finland-photo.jpg: Antasa — CC BY-SA 4.0 https://commons.wikimedia.org/wiki/File:Finnish_one_euro_coin.jpg https://creativecommons.org/licenses/by-sa/4.0/ chf-1-franc-1995-pair.jpg: JFS — CC BY 3.0 https://commons.wikimedia.org/wiki/File:1FR1995.jpg https://creativecommons.org/licenses/by/3.0 jpy-1-yen-1996-obverse.jpg: TiagoLubiana — CC0 https://commons.wikimedia.org/wiki/File:Moeda_de_1_iene_1996.jpg http://creativecommons.org/publicdomain/zero/1.0/deed.en jpy-1-yen-1996-reverse.jpg: TiagoLubiana — CC0 https://commons.wikimedia.org/wiki/File:Moeda_de_1_iene_1996_reverso.jpg http://creativecommons.org/publicdomain/zero/1.0/deed.en cny-1-yuan-obverse.jpg: Numista — CC BY 4.0 https://en.numista.com/1588 https://creativecommons.org/licenses/by/4.0/ cny-1-yuan-reverse.jpg: Numista — CC BY 4.0 https://en.numista.com/1588 https://creativecommons.org/licenses/by/4.0/ gbp-numista-physical-example.jpg: The Royal Mint, 2016 — Copyright; no open license stated on source https://en.numista.com/100658#example_15191 aud-1-dollar-obverse.jpg: brismike — CC BY-NC https://en.numista.com/2288 https://creativecommons.org/licenses/by-nc/4.0/ aud-1-dollar-reverse.jpg: brismike — CC BY-NC https://en.numista.com/2288 https://creativecommons.org/licenses/by-nc/4.0/ Archived original asset-library credits follow.
