Data Sources & Methodology

Where prices come from

Listed prices are indicative wholesale and retail market estimates compiled from major domestic dealer price lists, numismatic auction catalogues and historical sales records. Where sources differ, editors weigh recent, well-documented sales more heavily than asking prices.

What a listed price means

• Each price is a single indicative figure in Indian rupees for one issue at one grade.
• It is a guide, not a quote, valuation or offer to buy or sell.
• Real transaction prices vary with exact condition, toning, eye appeal, provenance and market demand.

Reader suggestions

Visitors can suggest price updates. Each suggestion records the coin, grade, suggested price, an optional source link and an optional note. Editors review suggestions against other evidence before approving or rejecting them. Approved suggestions update the listed price and its “last verified” date. We may reject suggestions that are unsupported, duplicated or look like spam. To limit abuse, the number of suggestions from one visitor is capped per hour.

Catalogue structure

Issues are identified by year, denomination, mint and variety, so different mints or varieties of the same year are listed separately and never overwrite each other. Rarity labels (Common, Scarce, Rare, Very Rare) are editorial indicators of how often an issue appears on the market, not formal census data.
