Decoding the 4 Crowns: UK Assay Office Marks
By law, all UK silver over 7.78g must bear 4 marks:
- Maker’s Mark (iTruWin’s ‘IW’ anvil)
- Metal Purity (925 = 92.5% silver)
- Assay Office:
- London: Leopard head
- Birmingham: Anchor
- Sheffield: York rose
- Edinburgh: Castle
- Date Letter (B=2024)
Spot fakes instantly: Misspelt ‘sterling’ or missing crowns? It’s plated.
The Paper Trick: Measure Ring Size in 60 Seconds
- Wrap paper strip around finger
- Mark overlap point
- Measure mm length
Pro tip: Knuckle larger than base? Size up. UK standard = H-M. Fun fact: Prince William wears size M!
