## What is Backstamp?

Photograph the mark on the bottom. Backstamp reads what that mark means: solid or plated, genuine standard or reproduction, 1890s or 1970s — and the typical sold range for pieces carrying it.

It isn't a list you search. Backstamp reads the mark you're holding, then shows you the exact characters it matched on — so you can check its work.

THE TRAPS IT CATCHES
Most people misread the same marks:

• "1847 Rogers Bros" — a founding year, not a date, and the piece is silverplate
• EPNS, Alpaca, nickel silver — no solid silver in any of them
• "22 KT GOLD" on china — that's paint, not bullion
• "WedgEwood" with an extra E — not the real firm

WHAT'S FREE
Everything: three decodes a day, with no account — plus the full marks library, the field guide and the British date-letter tool, permanently unlocked.

WHAT YOU GET
• A verdict in seconds, with the characters it matched on
• Purity standards, assay symbols, self-dating country marks, and the makers that matter
• A date-letter tool that turns one British hallmark letter into its candidate years
• A ledger of every find, with what you paid beside what the mark suggests
• Typing a mark works offline — library, guide and decoder live on your phone. Photo scanning needs a connection.

Backstamp is a research aid, not an appraisal. Estimates reflect typical sold prices for pieces in good condition — condition, pattern and size move them. Backstamp shows you the range and the evidence behind it, in seconds, on the mark in your hand.
