GreatCollections Scraper - Coin & Currency Auctions

Scrape graded coin and currency auctions from GreatCollections.com — one of the largest certified coin auction houses, having sold over 1,000,000 PCGS, NGC, CACG, ANACS and PMG certified coins and paper money.

Perfect for numismatic price research, grading arbitrage ("is it worth grading?"), populating a coin price database, building deal alerts, or complementing PSA/NGC/PCGS population data with live auction and realized-price comps.

What it does

Search GreatCollections and get clean, structured coin-lot data:

• Keyword search — e.g. Morgan Dollar, 1909-S VDB, PCGS MS-65, Gold Eagle, CAC, Toned
• Multiple queries — pass an array; each is searched separately
• Live auctions — current bid, bid count, time left
• Sold / realized prices — closed lots return their realized sold price
• Parsed attributes — grade, grading service, year, proof flag, CAC approval pulled from each title
• Optional detail pages — certification number, denomination, series, mintage, mint location, composition, strike type and industry number
