Stamps that mean the same thing
This purity may be struck into jewelry as any of: 416 / 10K (legacy). The mark differs by country and era, but the metal content is identical.
What 416 tells you
Pre-modern rounding of 10-karat gold. May appear on older US jewelry. Equivalent to current 417 for valuation purposes.
How to value it
The melt value of a 416 piece is gold spot price × 0.416 × 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
- Examine the stamp under a 10× loupe — genuine marks are crisp and evenly struck, not doubled or smeared.
- Confirm the mark reads 416 or an equivalent such as 10K (legacy).
- Photograph it in the Jewelry Identifier app to read the metal, hallmark, and any gemstones from the image.
- For a binding result, have an assay office or gemological lab run an XRF purity test.
* Frequently asked
FAQ
- Q. Is 416 the same as 10K (legacy)?
- A. Yes. 416, 10K (legacy) all denote the same material — 41.6% gold. Different markets and eras stamp it differently, but the purity is identical.
- Q. How much is 416 worth?
- A. Its melt value is the gold spot price × 0.416 × 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 416 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.
