By post

Please be sure to contact our stamp experts before sending any material by post. This is firstly because it will allow us to assume the postage costs and insure the package or registered letter – and secondly because there are some questions that can be cleared up quickly beforehand on the telephone.

If you send us your stamps by post, we will examine and evaluate them and then contact you to arrange a follow-up meeting to advise you further. Our experts will provide you with a professional market assessment. On the telephone, we discuss with you whether the stamps can be included in an auction. We can store material for auctions directly in our offices. Of course, we can also return the material to you if preferred. 

In your own home

If your stamp collection is particularly valuable or very extensive, there is always the option of arranging a house visit. Our stamp experts regularly travel around Germany and other European countries for this purpose. They will then arrange to come to your house and examine your material there. It is also possible to have to material transported to us with full insurance cover.


However, it is best to clarify by telephone beforehand whether a house visit is possible and, if so, when it should take place. Please feel free to call us to do so. You will receive advice during the first contact and then further information for a house visit. In this way, you can have the value of your complete personal or inherited collection determined by our experienced experts.
