Jacob J. Roosjen SRI
European Silver 

Jacob J. Roosjen is a specialist in antique silver and has been a certified valuer of silver and gold objects since 1989. After a 20-year-career at an international auction house, as Head of the Silver Department in Amsterdam and Milan, having also worked for the Geneva and Paris silver departments, he decided to found the Silver Research Institute (SRI®) in 2009, which he incorporated in his company, selling European antique silver objects from the16th to the 20th century. Keywords for the collection are quality, uniqueness, provenance and history. The current collection mainly comprises Dutch silver objects from the 17th to the 19th century.


His up-to-date archive and his extensive library enable Jacob J. Roosjen to do research on silver and gold objects thoroughly and advise private collectors, curators and clients in general.


The company is based in Breukelen, at a short distance from Amsterdam, where clients are welcome by appointment only. Jacob J. Roosjen is a member of Koninklijke VHOK, CINOA and TMV.
