"The man is a teacher in Berlin and said he wanted to show the objects to his students, who are doing a project on the Holocaust," town prosecutor Mariusz Slomka told AFP.
The 47-year-old was released after pleading guilty to theft, accepting a suspended prison sentence and agreeing to pay a fine, Slomka added.
It is not the first time someone has tried to steal an Auschwitz souvenir.
Several people have tried to make off with barbed wire while one particularly brazen gang walked out with the camp's infamous "Arbeit macht frei" ("Work makes you free") sign in 2009, sparking a global outcry.
The mastermind of that theft, Swedish neo-Nazi Anders Hoegstroem, was jailed for two-and-a-half years.
The metal sign was eventually recovered cut up into three pieces, leading museum officials to display a replica above the entrance.
Auschwitz-Birkenau has become a symbol of Nazi Germany's genocide of European Jews, one million of whom were killed at the camp from 1940 to 1945.
More than 100,000 others including non-Jewish Poles, Roma, Soviet prisoners of war and anti-Nazi resistance fighters also died there, according to the museum.
