[2] Pogrebetsky was director of the Department of Finance of "Centrosoyus" for the district of Irkutsk, Zabaikal, and Iakutsk provinces and Mongolia.

Around 1920, he relocated to Harbin, China, where he became head of the board of directors of the Chinese Eastern Railway Company.

[citation needed] Through his work and travels, Pogrebetsky was able to create an important collection of Chinese and Asian banknotes and coins.

He wrote (in Russian) Denezhnoe obrashchenie i denezhnye znaki Dal'nego Vostoka za period vojny i revoljutsii (1914-1924) (1924) (Money and bank notes of the Far East during the period of war and revolution), one of the first books on Chinese banknotes.

[2] The rest of the collection remained in family hands until 2015 when it was sold in two sales by Archives International Auctions in May and December.
