Instant Appraisal Playbook

Time is your enemy at estate sales. The best items disappear within the first hour, and you cannot afford to research every piece before deciding. This chapter provides a systematic approach to rapid valuation that balances speed with accuracy.

The Essential Toolkit

Carry these items to every sale:

1. Smartphone with Google Lens, eBay app, and WorthPoint (subscription recommended)
2. Jeweler's Loupe (10x magnification minimum)
3. Small Magnet (distinguishes brass from iron, tests for steel cores)
4. UV Flashlight (reveals repairs, identifies certain materials)
5. Measuring Tape (for furniture dimensions, rug sizes)
6. Notepad/Phone Notes (track items of interest)

The 60-Second Assessment Protocol

When you spot a potentially valuable item, run through this sequence:

Seconds 1-15: Visual Scan

• Overall condition (chips, cracks, repairs, missing parts)
• Signs of age (patina, wear patterns, construction methods)
• Maker marks, signatures, labels (flip it over, check the bottom)

Seconds 16-30: Quick Research

• Snap a photo and run through Google Lens
• Search eBay for similar items (filter by "Sold" listings)
• Note the price range for comparable condition

Seconds 31-45: Physical Examination

• Apply relevant tests (magnet, UV, weight assessment)
• Check for completeness (all parts, original accessories)
• Assess repairability if damaged

Seconds 46-60: Decision

• Calculate potential profit margin (aim for 3x minimum)
• Factor in shipping costs and platform fees
• Commit or move on

Material Testing Quick Reference

Metals:

• Magnet test: Sterling silver is non-magnetic; nickel silver is slightly magnetic
• Acid test: Carry a small kit for gold/silver verification
• Weight: Genuine precious metals feel heavier than plated items

Jet and Black Materials:

• Hot needle: Genuine jet smells like burning coal; plastic smells acrid
• Temperature: Jet feels warm; glass feels cold
• Weight: Jet is surprisingly lightweight

Pottery and Porcelain:

• UV light: Repairs often fluoresce differently than original material
• Sound: Tap gently—cracks produce a dull thud versus clear ring
• Marks: Photograph and research later if unfamiliar

App-Based Research Hierarchy

1. Google Lens: Instant visual matching for pattern identification
2. eBay App: Real-time sold listings for market pricing
3. WorthPoint: Historical auction data for rare items
4. Kovels: Maker marks and pattern identification
5. Replacements Ltd: China, crystal, and flatware patterns

• Practice the 60-second protocol until it becomes automatic
