I looked it up on Russian sites, it's apparently a known (slight) difference in the composition of the brass layer, but the sources that I could find make no mention of whether there was a particular difference between the two mints.
[Important note on the translation: the word "#1088;#1099;#1078;#1080;#1081;", which Google translated as "red", is actually supposed to refer to a color closer to orange, but its most common use is as a hair color, and the English name for that hair color is in fact "red".]

If we pay attention to the color of the coins presented here, the question arises: "Were they minted in the same metal?" The answer is the percentage of copper in the cladding alloy. If there is more copper, then the coin acquires a pronounced red color. Otherwise, the color of the coin is closer to yellow.
