Do you have SS-Totenkopfring but no Certificate of Authenticity?
As a book author and a long-time collector, I consider myself an expert in the field of SS-Totenkopfrings. I will gladly inspect your ring and in case of originality I will issue you a Certificate of Authenticity.
This option is particularly useful for collectors from Europe who are afraid to send a ring across the ocean. Transport is provided by Fedex and is very safe.
