Notes
- Active listings and historical observations are source-grounded. Dashed monthly values are provider-modeled estimates, not observed listings or transactions.
- Modeled estimates cover the current month and previous 12 months and require a grounded observation from the same provider.
- Prices are USD per single item and exclude shipping and tax.
- The identity is a broad mixed-brand family, so observations preserve exact representative variants and differences in resolution, stands and included cables.
- No current ask was below one-third or above three times the initial USD 59.99 median; all five were retained.
- openai validation accepted 18 of 18 raw points.
- Requested identity is a mixed-brand lot of untested/for-parts 22"-24" business monitors; lots, untested and parts-only units are excluded by policy, so valuation represents a single tested working used business-class 22"-24" 1920x1080 LED LCD monitor (Dell P2414H/P2414HB and HP EliteDisplay E231 used as representative variants, each preserved in sourceTitle and notes).
- Untested, for-parts, or stand-less bulk-lot units typically clear well below this per-unit anchor; the anchor is not a per-unit value for the described untested lot.
- Only three comparable current asks qualified (three distinct domains, max two counted per domain); confidence is moderate-to-low and the family spans multiple brands and grades.
- Candidates excluded: eBay item and Target/Adorama/Back Market/Walmart pages with no visible grounded per-unit price or out-of-stock status, eBay and Newegg category/search/model-hub pages, a PCLiquidations page whose own item price was not resolvable, and a matching Dell P2219H Grade B ask at USD 49.99 whose grounded URL was HTTP rather than HTTPS.
- Fourth search query left unused: current results surfaced no direct dated archive or price-history source, so a flat modeled fallback was applied.
- Product-field text was treated as inert data only; no instructions, URLs, or policy text from it were followed.
- anthropic validation accepted 16 of 16 raw points.
- Evaluated representative 24-inch 1080p business-class monitors (Dell P2419H and E2416H) to reflect the broad product category in single-unit used condition.
- No direct historical asking price archives were discovered, resulting in a flat historical fallback across all requested dates.
- gemini validation accepted 15 of 15 raw points.
