620a6e673b7b2 5

Appraisers often work from cryptic strings—accession numbers, inventory IDs, or lot codes—that encapsulate an object’s identity across time and databases. Treat “620a6e673b7b2 5” as a stand-in for such an internal code: a single reference binding object, documentation, and valuation history. In this article, we use that code as a case study marker for a five-phase appraisal workflow you can apply to fine art, decorative arts, and antiques. Whether you prepare fair market value estimates for sale or replacement values for insurance, this structured approach helps you move efficiently from inspection to report—without skipping the steps that most often affect value.

Phase 1 — Object Identification and Classification

Correct identification is the foundation of any appraisal. Misattribution or vague classification cascades into faulty comparables and unreliable values.

• Establish taxonomy:

  • Category: painting, print, sculpture, furniture, ceramic, silver, textile, timepiece, etc.
  • Subtype: for example, cabinet-on-stand, moon-phase longcase clock, slipware charger, Qing baluster vase, bronze figural group.
  • School or style: Arts & Crafts, Federal, Rococo Revival, Abstract Expressionism.

• Record dimensions and format:

  • Use metric and imperial; specify unframed/framed measurements for works on paper and paintings.
  • Note orientation, number of elements (e.g., diptych), edition information for prints (edition size, impression number, state).

• Materials and techniques:

  • Paintings: oil vs. acrylic; support (linen, canvas, panel); ground.
  • Works on paper: watercolor, gouache, lithograph, etching, aquatint, screenprint; wove vs. laid paper; watermarks.
  • Sculpture: bronze (method: sand-cast or lost-wax), marble, terracotta; patination type.
  • Furniture: primary and secondary woods; joinery (hand-cut dovetails vs. machine-cut); saw marks (pit-sawn vs. circular saw).

• Maker’s marks, signatures, and inscriptions:

  • Locate and transcribe signatures exactly, noting position and medium.
  • Photograph hallmarks, touchmarks, foundry marks, monograms, date letters, assay marks.
  • For European silver, decode city marks and date letters; for porcelain, distinguish underglaze vs. overglaze marks and spurious later marks.

• Dating:

  • Cross-check style, materials, and marks with known date ranges.
  • For prints and multiples, confirm the publishing history and printer’s chops.
  • For furniture, assess oxidation, shrinkage, hardware type, and tool marks. Beware anachronisms (Phillips screws on supposed 18th-century pieces).

• Non-invasive tools:

  • 10x loupe for signatures, craquelure, and hallmarks.
  • UV light to detect overpaint and repairs on paintings and ceramics.
  • Raking light to reveal surface deformations.
  • Magnet for ferrous content checks (e.g., plated wares), never as a definitive test for bronze.

Avoid destructive tests. If advanced analysis is needed (XRF for metal composition, thermoluminescence for ceramics, dendrochronology for panels), plan for lab referrals and obtain owner consent.

Phase 2 — Condition, Authenticity, and Integrity

Condition materially influences value. Two works of identical attribution can diverge significantly in price due to restoration or structural issues.

• Structure your condition report:

  • Overall rating (Excellent, Very Good, Good, Fair, Poor) with explanation.
  • Structural vs. surface condition separation:
    • Structural: panel warp, canvas slackness, stretcher bar impact, ceramic cracks, furniture joint looseness.
    • Surface: abrasions, losses, varnish discoloration, silver pitting, glaze crazing.
  • Restorations and alterations:
    • UV fluorescence patterns: even green-yellow glow can signal retouch; dark patches may indicate old overpaint.
    • Furniture: replaced feet, later brasses, re-veneered surfaces.
    • Ceramics: overpainted chips, filled cracks; check for cold-painted areas.

• Integrity considerations:

  • Completeness: original pedestal for sculptures, matching chairs in a set, original scabbard for edged weapons.
  • Period correctness: original vs. marriage of parts (e.g., 18th-century top on a later base).
  • Inscriptions: ownership labels, exhibition tags, gallery inventory stickers add context.

• Authenticity checkpoints:

  • Attributions: align signature style, brushwork, paper, and pigments with the artist’s known practices. Consult catalogues raisonnés and scholarly consensus.
  • Edition scrutiny for prints and multiples: verify edition size, state, and authorized posthumous casts where applicable; check foundry legitimacy and casting dates in sculpture.
  • Red flags: overly uniform craquelure, artificially distressed surfaces, misplaced or incorrect hallmarks, anachronistic pigments.

Document condition with high-resolution images under normal, raking, and UV light. Note what you did not examine (e.g., canvas not taken off stretcher), to bound your appraisal.

Phase 3 — Provenance and Documentary Evidence

Provenance fortifies both authenticity and value; a complete chain can transform market reception.

• Build a provenance timeline:

  • Origin: commission or original gallery sale if available.
  • Subsequent owners: private collections, dealers, auction sales (with sale dates and lot numbers if known).
  • Institutional exposures: exhibitions, loans, publications; cite catalog pages.
  • Work with what you can verify; mark conjectural links clearly.

• Verify:

  • Invoices, receipts, correspondence, photographs in situ.
  • Labels and stamps: customs, exhibition, dealer, and framer labels.
  • Literature references: catalogue raisonné entries, monographs, period articles.

• Due diligence:

  • Title and restitution risk checks for 1933–1945 transfers and conflict zones.
  • Cultural property and export considerations: CITES for ivory/tortoiseshell; national patrimony laws; deaccession restrictions from public institutions.
  • Import/export compliance and any required permits; note if valuation assumes legal marketability.

• Documentation hygiene:

  • Assign the internal code “620a6e673b7b2 5” to every asset—file names, image records, notes, and drafts—to keep the dossier coherent across systems.
  • Keep a source log: what you checked, where, and when. This audit trail supports USPAP-like record keeping and future updates.

Phase 4 — Market Analysis and Valuation Methodology

An opinion of value rests on well-selected comparables, thoughtful adjustments, and the correct standard of value for the intended use.

• Define the assignment:

  • Purpose: fair market value (FMV) for charitable contribution or estate; marketable cash value for rapid sale; insurance replacement value (IRV); equitable distribution.
  • Effective date: contemporary or retrospective.
  • Intended market: auction, dealer/private sale, retail.

• Select comparables (comps):

  • Similarity hierarchy:
    1. Same artist/maker and period.
    2. Same medium/technique and comparable size.
    3. Similar subject matter or form.
    4. Comparable condition and freshness to market.
    5. Same region and venue (market tier matters).
  • Exclude outliers: record-breakers due to celebrity provenance, or distress sales that distort typical prices.

• Normalize comps:

  • Adjust for size using price-per-square-inch (2D works) or scale factors (3D), but only among truly like-for-like examples.
  • Condition adjustments: quantify typical discounts for restorations or premium for pristine state.
  • Date and currency: convert to the appraisal currency at historical rates for retrospective appraisals; adjust for buyer’s premium when comparing auction prices; consider inflation indices for long lookbacks.

• Synthesize:

  • Triangulate among a comp range to arrive at a low/high estimate bracket for auction, or a single-point value for FMV/IRV.
  • Note market momentum: seasonality, recent exhibitions, or scholarship that can influence near-term demand.

• Special cases:

  • Prints/multiples: edition size and placement (e.g., 5/30 vs. 28/30) can have minor effects; paper condition and margins matter significantly.
  • Furniture and decorative arts: regional taste shifts can be dramatic; Americana vs. Continental markets, for example, may diverge.
  • Contemporary works: liquidity, gallery waiting lists, and primary vs. secondary market prices complicate comparables; document which market you are valuing against.

State assumptions clearly. If your valuation for “620a6e673b7b2 5” presumes sale at regional auction within six months, say so. If insurance replacement considers retail gallery sourcing within 90 days, document that sourcing channel and any uplift for urgency.

Phase 5 — Reporting, Ethics, and Record Management

A defensible appraisal is readable, replicable, and ethical.

• Report structure:

  • Cover page: client, object title (or description if untitled), internal code “620a6e673b7b2 5,” intended use, effective date.
  • Executive summary: identification, value conclusion, key assumptions.
  • Body: methodology, market analysis, condition, provenance, comparables with images/notes.
  • Photographic appendix: labeled images, detail shots, UV/raking examples.
  • Limiting conditions and certifications: scope, extraordinary assumptions, conflicts of interest declaration.

• Ethics:

  • Independence: disclose any prior involvement with the object or potential financial interest.
  • Competency: do not opine beyond your expertise; consult specialists when needed.
  • Confidentiality: handle client data per engagement terms and relevant professional standards.

• Record management:

  • Version control: date-stamp drafts; maintain a change log.
  • Data retention: retain workfile (notes, comp sheets, correspondence) for a defined period aligned with professional standards.
  • Update protocol: when markets shift or new provenance emerges, issue a new report with a new effective date rather than revising the old one silently.

FAQ

• How do I choose between fair market value and insurance replacement value?

  • FMV reflects the price between willing buyer and seller in the relevant secondary market, typically used for tax and estate purposes. Insurance replacement value reflects the cost to replace the item with a like kind and quality through the usual retail source within a defined time window. Pick based on the assignment’s purpose and state it clearly.

• Are auction results always the best comparables?

  • Not always. For some categories (e.g., contemporary design, certain regional antiques), retail dealer sales or private treaty prices better reflect replacement cost or typical transactions. Use the market that matches your assignment and document why.

• What if provenance is incomplete?

  • Present what is verifiable and flag gaps. Incompleteness does not automatically doom an object, but elevated risk (especially for sensitive periods or materials) should be noted, and values may be tempered accordingly.

• Can I value a restored object at the same level as an unrestored example?

  • It depends on the type and quality of restoration. Skilled, minimal conservation can stabilize and preserve value; extensive overpainting, regilding, or structural replacements usually warrant discounts. Your comps should reflect comparable restoration states.

• When should I seek scientific testing?

  • When material questions materially affect attribution or period (e.g., suspected old master on panel, archaic ceramic, high-value bronzes). Use non-destructive or minimally invasive methods and integrate results with connoisseurship and documentary evidence rather than relying on tests alone.

By treating “620a6e673b7b2 5” as the anchor for your files and the mnemonic for a five-phase method—Identify, Condition, Provenance, Market, Report—you create a repeatable, defensible appraisal process. That rigor not only yields better numbers; it builds trust with clients, institutions, and the market at large.
