The shift to .750 fineness for Russian silver fractionals in the late 1850s was a deliberate fiscal adjustment under the Ministry of Finance, reducing silver content across small denominations to curb hoarding and bring coinage costs in line with the ongoing strain of post-Crimean War debt. Russia had emerged from that war financially exhausted, and the 1859 recoinage was one of several quiet measures taken before the more dramatic monetary reforms of the 1860s.
The two-year window for this type reflects rapid policy revision rather than a planned series run.
