Why is there a $1 overprint on this Russian occupied Finnish stamp?

  I guess in that end of the planet, Russia was occupying everybody at one point or another.  In this case, it was the good people of Finland who were occupied.  Throughout the course of this blog, I will be doing some research as to why and when that happened. Good chance this is a 1917 stamp from that period.  The similar stamps to this that I do see are imperforated....this one not so, yet another reason why I think it is fake.

Why the 1 dollar overprint?  What could that mean?  My first guess is always a fake/forgery of some kind, but who knows?  I have found the particular stamp on delkampe.net and even ebay but of course, without the overprint and without the perforations.   It is the overprint which makes it unique and special, if it is in fact unique or special  The color is great, the margins excellent, the perforations neat...a very good stamp.  Of note, I have a full collection of overprinted stamps that would take the rest of my lifetime to research one by one, all with their unique history and likely speaking to more occupations/

Specific to the occupation of Finand by Russia, I copy this from Wiki.  The policy of Russification of Finland (1899–1905 and 1908–1917, called sortokaudet/sortovuodet(times/years of oppression) in Finnish and förtrycksperioderna in Swedish) was a governmental policy of theRussian Empire aimed at limiting the special status of the Grand Duchy of Finland and possibly the termination of its political autonomy and cultural uniqueness. It was a part of a larger policy of Russification pursued by late 19th–early 20th century Russian governments which tried to abolish cultural and administrative autonomy of non-Russian minorities within the empire. The two Russification campaigns evoked widespread Finnish resistance, starting with petitions and escalating to strikes, passive resistance (including draft resistance) and eventually active resistance. Finnish resistance to Russification was one of the main factors that ultimately led to Finland's declaration of independence in 1917.

So much history, so much to know and understand.  It seems most every stamp leads to a story about conflict and occupation, and war, and freedom.   Why is it that so many people in our country live in a bubble, thinking the world started around 1776 if not 1960?  Why is it that much of the great history of the people of other countries gets minimized by the chest thumping USA populace?  Why are we so insecure as a people such that we have to discount history and the accomplishments of people who lived under far adverse situations, yet made do, made love, made family, and made war and somehow came out the other side?  Why is there a $1 imprint on this stamp?   And why is it not a one of a kind rarity that would sell for $100,000 at auction?  Too many questions and not enough answers.
