Finnish coin promts to revisit the history of Napoleonic wars

While browsing e-bay, I found it interesting that some Finnish coins from early 1900s had a a very similar obverse to Russian coins of the same time period. At first, I attributed it to some friendly cooperation, sharing of designs or minting know-how between neighbors, or a simple coincidence. However, as soon as I looked at the reverse and saw Russian Imperial coats of arms, I wanted to learn more. I knew that the relationship between these countries was at times "complicated" (the Winter War of 1939, etc), but somehow, I missed the lesson on the war of 1808 and how after beating Sweden, Russia converted the eastern third of Sweden into the Grand Duchy of Finland (an autonomous part of the Russian empire). It also prompted me to learn about other conflicts of that era. In school, I viewed the war of 1812 as mainly a French invasion of Russia, but a closer look revealed a complicated web of conflicts comprised by Napoleonic Wars that started years earlier. It was truly a World War (a WW 0) that involved everyone form Russian to Sweden to Turkey, and even the US. Interestingly, here in the US, the war of 1812 is a war between the United States and United Kingdom, but I guess ultimately, it is directly related since British probably wouldn't impress American sailors into service if their navy hasn't been constantly depleted by battles with Napoleon. While a few Wikipedia articles and YouTube videos don't do justice to these topics, I am less ignorant than I was few days ago and that's a start.

At the end, I had to buy both:

Good choice and nice pieces.
We have had our own Markka since 1864 but at that time we were the Grand Duchy. We got our independence on 6 Dec 1917.
