10 Roubles S.I. Bolgarin

Transnistria — officially unrecognized by any UN member state — operates its own central bank and issues collector coinage as a soft assertion of administrative independence from Moldova. The Bolgarin series honors Semyon Ivanovich Bolgarin, a figure in the region's Soviet-era agricultural and political history, the kind of local commemoration that Tiraspol's numismatic program favors heavily over broader historical subjects.

The Transnistrian Republican Bank has issued silver collector pieces consistently since the 1990s, partly as revenue generation given the territory's constrained hard currency position.
