}cotation — Grille de rachat du jour
Today's public buying grid of Gold & Silver Company, timestamped: gold by fineness (9K, 14K, 18K, 22K in EUR per gram; 24K/999 refers to the live rate) or by coin/bar (napoleon_20f, pesos_50, argent_lingot_1kg in EUR per piece). Optional weight in grams or number of pieces gives an indicative amount; `objets` quotes several items in one call with a total. The firm price is set at the office after weighing and fineness check. Source: the public grid on the website, never internal tools.

Qualifies the visit (nature of the items, quantity or approximate weight, provenance, private or professional) and orients it: visit sheet with opening hours below 1 kg of gold; appointment required from 1 kg of gold. When qualification data is missing, returns the questions still to ask (questions_manquantes). Never a price and never a valuation: use cotation for the public buying grid.
