This paper reports the result of the chemical analysis of the Chinese coin Yongle Tongbao owned by Khabarovsk Regional Museum named after N.I. Grodekov. It was found that this Yongle Tongbao is the officially minted coin. This coin was excavated in Krasnokurovka burial ground in the Khabarovsk Territory. The burial ground was made under the Pokrovka culture (from the 9 th to the 13 th centuries). However the Yongle Tongbao, which was first minted in 1408, was discovered in the mound No. 30 of Krasnokurovka burial ground. So, it is necessary to reconsider the end period of the Pokrovka culture.
