What LION_PASSANT tells you

British assay mark: walking lion in profile. Indicates sterling silver (925) since 1544. One of the four mandatory British hallmarks (sponsor + standard + assay office + date letter). After 1822 the lion's head changes from facing forward to in-profile.

How to value it

The melt value of a LION_PASSANT piece is silver spot price × 0.925 × weight (g). A buyer typically deducts 5–15% for assay, refining, and margin, so the cash offer lands just under that figure. Stones and complex settings are usually excluded from the metal weight.

How to check it yourself

  1. Examine the stamp under a 10× loupe — genuine marks are crisp and evenly struck, not doubled or smeared.
  2. Confirm the mark reads LION_PASSANT or an equivalent such as LION.
  3. Photograph it in the Jewelry Identifier app to read the metal, hallmark, and any gemstones from the image.
  4. For a binding result, have an assay office or gemological lab run an XRF purity test.

FAQ

Q. Is LION_PASSANT the same as LION?
A. Yes. LION_PASSANT, LION, Lion Passant, WALKING LION all denote the same material — 92.5% silver. Different markets and eras stamp it differently, but the purity is identical.
Q. How much is LION_PASSANT worth?
A. Its melt value is the silver spot price × 0.925 × the weight in grams. Buyers then deduct roughly 5–15% for refining and margin, so a quoted buy-back price sits a little below that theoretical figure.
Q. How do I confirm a LION_PASSANT stamp is genuine?
A. Look at the mark under 10× magnification for crisp, even strikes, cross-check the weight-to-volume ratio against the expected density, scan it with the Jewelry Identifier app, and — when it matters — have an XRF test done by an assay office or gemological lab.
