AI Cataloging for Coins & Currency
Coin cataloging carries unique liability because grade determines value and grade cannot be assigned from photos. A 1909-S VDB Lincoln cent in VF-30 is worth $900 — in VG-8, it is worth $350. Gavelist identifies denomination, date, mint mark, and type while explicitly avoiding grade claims, producing descriptions that are accurate and legally safe. Items that may warrant professional grading are flagged for your review.

Why Coins & Currency Cataloging Is Challenging
- Grading cannot be done from photographs — even slight differences in wear affect value by multiples
- Counterfeit coins are increasingly sophisticated — Chinese-made fakes of key dates are widespread
- Mint marks are tiny and require macro photography to identify — the 'S' on a Morgan dollar changes value by 10x
- Cleaning destroys numismatic value but is invisible to non-collectors — descriptions must not claim 'uncirculated' based on shininess
- Bulk coin collections require strategic lotting — individually listing 200 common-date wheat pennies wastes time
What Gavelist Identifies from Photos
- Denomination, date, and mint mark identification from obverse and reverse photos
- Coin type classification — Morgan dollar, Walking Liberty half, Mercury dime, Buffalo nickel
- Metal composition indicators — silver vs clad, gold vs gold-plated
- Key date and semi-key date flagging for valuable varieties
- Currency series, denomination, and notable serial number patterns
- Holder and slab identification — PCGS, NGC, ANACS graded holders

Photography Tips for Better AI Results
- 1Photograph both obverse and reverse of every coin — both sides carry identification and value information
- 2Use macro mode and even lighting to capture mint marks and date digits clearly
- 3For slabbed coins, photograph through the holder showing the grade label
- 4Avoid cleaning or handling coins with bare hands — fingerprints reduce numismatic value permanently
