Mongolian Orders, produced in very limited quantities on Soviet Mints during 1926-1959, are arguably among the most beautiful awards ever made. Constructed from precious metals with intricate use of multi-color enamels, and composed of multitude of parts, their design is massive and complex, bringing a true joy to the phaleristic aficionados. Until only a few years ago, there were virtually no information on Mongolian Orders, their manufacturing issues and types. Latest and very recommended published work on a subject is "The Orders and Medals of the Mongolian People's Republic (1924-1992)", 2010, by Khuujii Urnukh, which has the most up to date information, as well as great illustrations. So, HAPPY COLLECTING!!!
Systematic Reference Tables
Screwback Types and Variations 
This website is the first ever attempt to systemize Mongolian Orders from collector's perspective. Although dealing with screwback types only, it still gives a collector a broad and comprehensive reference source, unavailable elsewhere. Tables are based on all publications known to date, plus additional research and years of accumulated illustrations and colleague's collective effort. As always, any help or corrections are most welcome.
