An Overview of
Our Favourite Online Resources
The British Museum's online database.
'Vad Är Den Värd': Search engine for hammer prices from Nordic auction houses
English sterling silver date marks and makers marks: Very helpful for identifying the year/city marks on your British sterling silver.
'Online Encyclopedia of Silver Marks, Hallmarks & Makers' Marks': Large index of international silver marks from almost any country you could want.
I particularly like to use it for Danish makers marks: https://www.925-1000.com/dm_Assay.html
'Danish Glassworks Reference Museum': An amazingly thorough online archive of Holmegaard, Kastrup and Funen (Fyn) Glassworks.
