Sales by Private Treaty

In addition to Strauss & Co’s core auction business, at our total discretion, Strauss & Co can also arrange the swift and discreet sale of select items privately. Our experts will coordinate the private sale or purchase at the best possible price.


We specialise in appraisals of large private collections and can provide you with a detailed description of each item. This service is available if you are considering a sale or if you require the information for family division, insurance or probate.

Catalogue Subscriptions

Our beautifully illustrated catalogues are valuable sources of information which may be purchased for individual sales or in subscription packages. Each catalogue is mailed out in advance of the sale providing clients with the time to consider any items in which they may be interested.
