A Real Sterling Silver Ingot Explained


Sterling silver ingot with five British hallmarks: sponsor’s mark, Sheffield rose, lion passant, 1977 date letter C and commemorative mark.


I recently acquired this sterling silver ingot during an office appointment in Haywards Heath. This is a useful example of a fully hallmarked piece where every stamp tells a clear story about its origin and history.


Understanding the Hallmarks


This ingot bears 5 clear hallmarks. Here’s what each mark tells us.


1. Sponsor’s / Maker’s Mark

The sponsor’s mark shows the registered person or company that submitted the piece for hallmarking. In this case: SMC°.


2. The Rose (Sheffield Assay Office)

The rose is the mark of the Sheffield Assay Office. It tells us where the piece was hallmarked, confirming it was tested in Sheffield.


3. The Lion Passant (Sterling Silver Standard Mark)

The lion passant is the traditional standard mark for sterling silver. It confirms that this ingot is sterling silver (92.5% pure silver).


4. C (Date Letter)

The letter C is the date letter. The letter, its style (font) and the surrounding shield shape are used together to identify the year the piece was hallmarked. The letter does not indicate the assay office.


5. Commemorative Mark

They record a specific historic occasion rather than indicating the metal's purity or maker.



What Are Silver Hallmarks?

Hallmarks are official stamps applied by an Assay Office to precious metals. They guarantee the metal is genuine and tell us important details about where and when the piece was tested.


Sterling Silver vs Silver Plate

The lion passant confirms this ingot is sterling silver (92.5% pure silver). Silver plate items do not have a full set of hallmarks like this.


What This Means When I'm Valuing Silver

When I examine pieces like this, a complete set of clear hallmarks allows me to establish much more than whether an item simply looks like silver. I can use the marks to confirm the silver standard, identify the assay office and help establish when the piece was hallmarked. This is one of the first things I look for when assessing silver.


Not Sure What Your Silver Hallmarks Mean?

If you have a silver ingot, piece of silver or an unfamiliar hallmark, you're welcome to send me a clear photograph via WhatsApp. I can take an initial look and let you know whether it's something worth investigating further.
