622afaba13128
Collectors and appraisers encounter cryptic strings—stencils on a crate, graphite on a stretcher, pen on a label—that look like 622afaba13128. Whether it’s an inventory code, a dealer stock number, or a museum accession, that fragment can unlock provenance and, ultimately, value. This guide explains how to turn a code like 622afaba13128 into research leads, how to weigh condition and authenticity evidence, and how to convert findings into a defensible valuation.
What a code like 622afaba13128 can tell you
Marks, labels, and numbers fall into families. Identifying which family you’re dealing with guides your next steps.
- Museum/Institution accession numbers: Typically structured (year.collection.sequence). Example forms: 1962.28.131, 62.2.131, or alphanumeric. Found on stretcher, verso, base, or an old catalog tag.
- Dealer stock numbers: Often alphanumeric, sometimes with dashes or periods. Can repeat across multiple artworks in a shipment. Located on tags, frames, or old invoices.
- Auction house lot/stock numbers: Shorter numbers, sometimes stenciled on the stretcher or underside, accompanied by sale date stickers or colored dots.
- Shipper or customs numbers: Stencils on crates; can include routing codes, consignor initials, or destination abbreviations. Useful for dating movement between countries.
- Foundry or printer marks: For sculpture/prints, often with edition numbers (e.g., 13/125) plus foundry stamps or chop marks.
- Collection and gallery labels: Named labels with addresses, phone numbers, or logo variants that help date a period of ownership.
Initial triage steps:
- Record exact transcription, including spacing, punctuation, font style, and color. Photograph in context with scale.
- Note location and substrate: handwritten on canvas verso differs in weight from a tape tag on a frame.
- Check for palimpsest: earlier crossed-out numbers can signal previous owners and repair history.
- Consider pattern logic. 622afaba13128 might be parsed as 622a-faba-13128 (shelf-location-sequence) or a continuous dealer code. Don’t force a fit; list plausible families.
Evidence weighting:
- Tied to a known institutional system with corroborating marks (e.g., a registrar stamp)? High reliability.
- Matches a known dealer coding style and label design? Moderate to high.
- Isolated handwritten numbers with no corroboration? Low; treat as leads, not proof.
From mark to provenance: building a chain of custody
Provenance is the backbone of authenticity and risk assessment. Start from what you see on the object and radiate outward.
- Assemble a timeline scaffold: current owner → prior sale (invoice, auction catalog) → dealer/collector labels → shippers/customs → institutional notes. Plot known dates and identify gaps explicitly.
- Align marks with documentary evidence: If 622afaba13128 appears on a frame and the family retains an invoice with a similar code or dealer name, you’ve anchored that segment of provenance.
- Cross-reference catalogues raisonnés, artist monographs, and exhibition checklists. Look for matching dimensions, medium, inscriptions, and photographs. Verify whether numbers on the object correspond to checklist numbers or internal control numbers.
- Photograph all labels and inscriptions under raking and UV light. Inconsistent fluorescence around a number may indicate overpainting or alteration.
- Red flags: erased or rewritten numbers, conflicting dimensions between labels and object, labels applied to a later frame rather than the artwork proper, mismatched materials (e.g., a 1920s dealer label on a frame molding type introduced in the 1970s).
Grading provenance strength:
- Primary, contemporaneous documents (invoices, exhibition labels with dates) tied directly to the object’s unique descriptors carry the most weight.
- Secondary references (oral histories, memoirs) can support but should not stand alone.
- An orphan code like 622afaba13128 is a lead—valuable only when triangulated with other evidence.
Provenance and risk:
- Pre-1946 European works need WWII-era scrutiny for gaps and forced sales.
- Archaeological and ethnographic items require cultural property due diligence.
- Wildlife materials (ivory, tortoiseshell) invoke species-protection rules.
Condition and authenticity: technical work that changes value
Condition isn’t cosmetic; it’s financial. Worn gilding on a frame, an overcleaned sky, or an unstable bronze patina can swing value by double digits.
Core observations:
- Structure: For paintings, record support (linen, cotton, panel, board), stretcher type, keys, and any relining. For sculpture, note casting method (sand vs. lost-wax), seams, core pits, and chasing.
- Surface: Map craquelure types, abrasions, cupping, tenting, and retouching. For works on paper, note foxing, mat burn, and paper type/chain lines.
- Inscriptions and signatures: Assess execution relative to artist’s known hand. Check whether a signature sits atop later varnish (red flag).
- Frames and mounts: Period frames can add value; anachronistic frames can mislead. Label the frame separately as included or excluded in value conclusion.
Simple technical aids:
- UV light: Locates retouching and varnish differences. Note that not all pigments fluoresce consistently.
- Raking light: Reveals planar distortions and craquelure patterns.
- XRF/FTIR (via specialists): Identifies pigments and binders to confirm period plausibility. Example: titanium white suggests post-1916 usage; its presence in a “1800” painting is a concern.
- Dendrochronology (for panel paintings): Can date wood felling; a terminus post quem helps bracket possible creation time.
Condition to value translation:
- Stable, original surfaces command premiums; extensive overpaint or structural repairs warrant discounts.
- Typical adjustments for common categories might range from -5% for routine edge retouch to -30% or more for major overpaint or structural instability.
- Restoration can increase marketability but doesn’t always “add” value net of cost; it often reduces discount rather than creating a premium.
Authentication context:
- Connoisseurship and technical evidence complement each other. A plausible hand with implausible materials is a no-go.
- Attributions carry confidence levels (by artist, workshop of, circle of, follower of). Each tier corresponds to very different market bands.
Valuation methodology that anchors numbers
Start with scope: define the intended use and type of value.
- Fair Market Value (FMV): For tax and many estate contexts; willing buyer/seller, no compulsion.
- Retail Replacement Value (RRV): For insurance; cost to replace with a like item at retail in a reasonable time.
- Marketable Cash Value or Forced Liquidation Value: Reflects discounts for quick sale or limited market exposure.
Select the relevant market level:
- Primary (from the artist/gallery), secondary retail (dealers), or auction. Choose based on the object’s typical trade channel.
Comparable selection:
- Same artist or maker where possible; else same school/period/maker circle.
- Align medium, size, date, subject, signature status, and condition.
- Prefer sales within the last 3–5 years; include older comps only if the market is thin.
Adjustments (qualitative → quantitative):
- Size: Scale value nonlinearly; larger works often command disproportionately higher prices, but subject desirability can override.
- Medium: Oil on canvas vs. oil on board vs. watercolor vs. print; each has distinct price ladders.
- Date and period: Peak-period works vs. late or early period.
- Subject: Portrait vs. landscape vs. marine; iconic subjects carry premiums.
- Provenance/exhibition/publication: Named collections and exhibitions can add 5–25% depending on significance.
- Condition: Deduct per conservation burden and risk.
- Market timing: Uptrends/downtrends; bracket values rather than fixating on a single point.
Worked example (simplified):
- Subject work: Oil on canvas, 61 x 76 cm, stable original surface, minor edge retouch, plausible provenance chain including a 1970s dealer label with code similar to 622afaba13128.
- Comp A: Same artist, 55 x 70 cm, similar subject, sold 18 months ago at auction for 24,000 (hammer + premium). Smaller size (+10% to subject), slightly inferior condition (+5%), weaker provenance (+10%). Adjusted: 24,000 × 1.25 = 30,000.
- Comp B: Same artist, 65 x 81 cm, different but popular subject, sold dealer retail at 48,000 two years ago. Larger size (-8% to subject), stronger subject (-12%), similar condition (0%), gallery retail premium (-10% if valuing at FMV/auction level). Adjusted to auction-level equivalent: 48,000 × 0.70 = 33,600; then size/subject net -20%: 26,880.
- Comp C: Workshop piece, 61 x 76 cm, sold 10,000. Attribution difference (+60% to subject for full-artist status), better condition (-5%). Adjusted: 10,000 × 1.55 = 15,500.
Bracket and reconcile:
- Place subject between Comp C and A/B, weight A and B more heavily for attribution parity. A: 50% weight (30,000), B: 35% (26,880), C: 15% (15,500) → Indicated FMV ≈ 27,900. Round to 28,000 with a stated value range (e.g., 25,000–31,000) acknowledging market volatility and data limits.
Key cautions:
- Don’t use asking prices as comps; rely on verified realizations.
- Include buyer’s premiums when comparing like-for-like; be consistent across comps.
- Adjust currencies and dates for inflation where relevant. Note assumptions.
Reporting, ethics, and risk management

Practical checklist: turning 622afaba13128 into an appraisal
- Photograph the mark in situ with a scale and capture the entire verso/base.
- Transcribe the code exactly; note letter case, separators, color, and tool (pencil/paint/stencil).
- Map all labels and inscriptions; sketch a location diagram.
- Measure the object precisely (metric and imperial), unframed and framed; record stretcher/frame details.
- Conduct UV and raking-light examination; document retouch and surface anomalies.
- Draft a preliminary provenance timeline; list gaps and targeted research actions.
- Identify market level (auction/dealer/primary) appropriate to the object and value purpose (FMV/RRV/etc.).
- Select 5–8 comparables; narrow to 3–5 best after screening for medium, size, subject, and date.
- Normalize comp data (premiums, currency, inflation); apply and justify adjustments.
- Reconcile to a value conclusion with a clear range and effective date.
- List assumptions/limiting conditions and note any pending tests or verifications.
- Compile a concise report with photos, marks (including 622afaba13128), provenance, condition, comps, and signed certifications.
FAQ
Q: Is a code like 622afaba13128 proof of authenticity? A: No. It’s a lead. Only when a mark aligns with verified documentation (e.g., an accession system, dealer records) and matches the object’s specifics does it contribute to authenticity. Treat isolated codes as prompts for further research.
Q: How much value can provenance add? A: It depends on significance. Routine dealer ownership might have little impact; a documented exhibition history or notable collection can add 5–25% or more. Conversely, problematic or missing provenance in sensitive categories can depress value or make sale impossible.
Q: Should I restore before appraising? A: Usually no. Appraise as-is, then model post-conservation scenarios if needed. Restoration can improve marketability, but costs and risks must be weighed; over-restoration can reduce value.
Q: Can I use asking prices as comparables? A: Avoid them. Use realized prices from documented sales. If you must reference asking prices due to a thin market, disclose them clearly and apply a realistic negotiation discount, explaining your rationale.
Q: How long does a credible appraisal take? A: For straightforward objects with available comps, a few days. For complex attributions or significant provenance research, expect weeks. Build time for verification of marks, including codes like 622afaba13128, and for obtaining high-quality images and condition data.
By treating every code, including 622afaba13128, as a structured research opportunity—and by translating findings into transparent, market-grounded analysis—you build appraisals that stand up to scrutiny, serve clients, and protect your professional reputation.
