Hacoco is built around public auction records, artist identity data, realized sale outcomes, and normalized artwork metadata. Transaction records are treated as evidence only when the source, sale date, realized price, medium, and dimensions can be interpreted with sufficient clarity.
Before pricing begins, the artist name is resolved against canonical names, alias variations, spelling differences, and market history. This prevents a collector-facing valuation from starting with a fragile text match.
Comparable evidence is filtered by medium match, scale proximity, sale recency, and source quality. Records can support the range, remain directional, or be down-weighted when the work differs materially from the submitted artwork.
Canvas, paper, board, print, and mixed-media markets can price differently even for the same artist. Hacoco normalizes price per area where appropriate, reviews size bands, and excludes or discounts outliers before calculating the range.
Public auction realization is modelled separately from private market value. Auction can create competitive tension, but it also introduces reserve, timing, venue, and public failure risk. Private sale may protect discretion and route control.
Confidence reflects evidence depth, comparable consistency, market liquidity, and the quality of artwork details supplied. Sparse records, seed-only identities, unusual media, high-value estimates, and private-sale recommendations may trigger advisory-led pricing. Hacoco outputs are market-intelligence estimates, not guarantees, formal appraisals, authentication opinions, or offers to purchase.
