A collection of rare artefacts from Nazi Germany including a telegram sent by Adolf Hitler went on display on Tuesday ahead of their auction in Chesapeake at the end of April.

The sale includes historical documents such as the hand-written notes by chief German negotiator and naval admiral Hans-Georg von Friedeburg of the demands made by allied forces during the surrender of Germany in 1945.

Auctioneer Bill Panagopulos said a telegram exchange between Hitler and Field Marshal Ferdinand Schorner is estimated to be worth $60,000-80,000 (€53,000-71000) because of Hitler's declaration that "I will not leave Berlin."

"This document is of great historic importance being the only written acknowledgement by Hitler that he would stay in Berlin. It's the only one that I have seen, the only one that we know of," he said.

Other items including the original 'SS' issued overcoat Hans Heinrich Lammers are also featured in the extensive collection.
