MOSCOW (AP) — The U.S. has returned nearly 30 documents from the 18th and 19th centuries to the Russian government.

During a Thursday ceremony at the ambassador's residence in Moscow, a branch of the U.S. Homeland Security Department repatriated 28 documents ranging from imperial decrees to architectural drawings that were stolen and recently recovered in the United States.

The materials were stolen from Russian state archives and vary in value. One recovered document, a decree issued by Russian Emperor Peter the Great, was found in the possession of an individual from Reno, Nevada, and is valued at more than $12,000, according to Jason Cassidy, a Homeland Security official familiar with the case.

The U.S. has repatriated stolen Russian artifacts in the past as part of ongoing cooperation with Russian law enforcement authorities.
