  "accessNotes": "Plain HTTPS with the RareIndex user agent on www.cleansweepauctions.com (robots.txt: Disallow only account/cart/checkout/forum/customer paths, no Crawl-delay; we keep 2 s between requests). Pages read: /past-auctions (one entry per closed monthly auction, April 2008 → present, ~200 months), /past-auctions/<month-year>?page=N (50 lot links per page, server-rendered) and each lot page /past-auctions/<month-year>/<slug>, whose 'Winning bid: $X' is the hammer price; the auction rules add a 22 % buyer's premium on top, so sales are stored with buyerPremiumIncluded=false and buyers_premium_pct=22 in metadata. The archive dates lots only by auction month: saleDate is the first day of that month (UTC) with metadata.sale_date_precision='month' and confidence 0.7. Titles often end in a bare grade number without a grading company; no grader is inferred in that case. The live-auction host marketplace.cleansweepauctions.com (Crawl-delay 15, AJAX price grid, bidder accounts) is never crawled — only its public image URLs are referenced. 0 credits.",
