New Horizons: Welcoming Stamps, Coins & Watches to Antiqval

The thrill of discovery just got even richer. This month we’ve unlocked three of the most asked-for categories—stamps, coins, and watches—bringing centuries of artistry, minting mastery, and mechanical ingenuity into the Antiqval fold.

Expanding our coverage is never as simple as flipping a switch. Each domain carries its own quirks: the microscopic printing varieties that separate a common definitive from a philatelic holy grail; the hairline die cracks that turn everyday pocket change into a key-date rarity; the subtle dial aging that can add—or erase—thousands from a vintage chronograph. Sourcing reliable market data, teaching our vision models to notice these subtleties, and packaging insight in a way that feels instant and intuitive is equal parts science, craft, and sheer persistence.

Yet challenges were made to be tackled. Our updated pipeline now cross-checks high-resolution imagery against curated reference sets, weighs recent auction results, and surfaces a confidence-scored value range—all in under a minute. You still get the clean JSON you’re used to, plus category-specific tips to help you photograph, store, and insure your treasures.

What hasn’t changed is our promise of transparency. When the data is thin, we tell you. When grades are borderline, we color the estimate accordingly. And as always, every appraisal feeds back into our learning loop so the next one is sharper.

Whether you’ve inherited a shoebox of foreign airmails, found a jar of silver quarters, or spotted your dream dive watch, Antiqval is now ready to give each piece the attention—and the price context—it deserves. Thanks for taking this journey with us; we’re only just winding the mainspring.
