Bonedigger, I can say for sure, that the Finnish 10 Markkaa note, because it is a used one, has a value of exactly 1.68 euros or around US $1.18...
This 10 Markkaa banknote is not valid anymore, due to conversion into Euros. BUT the Bank of Finland (in Helsinki) will redeem old Markka-notes until February 29th, 2012, at their face value with a fixed rate of 1 EUR = 5.94573 FIM.
If it was UNC note, some collectors might pay double the face value for it.
Oh, and for others, who happen to possess some finnish banknotes, especially the ones with larger denominations. These usually carry larger premiums over their face value, than smaller denominations. Also, larger banknotes from 1970s tend to be worth a lot more, than their face value. For example an UNC/AU 1975 500 markkaa banknote (that the Bank of Finland will redeem for 84.10 euros) is actually worth 200-300 euros!
Then, the replacement notes, these also might carry a significant premium over their face value, so keep them if you have them! IIRC, there are some replacement notes, that might have a face value of 10 Markkaa, but their collector value might be around 200 euros!
The Standard Catalog of World Paper Money does not list different signature variants (IIRC) at all, but just to mention, there are A LOT of them. Some of them are VERY rare, some quite common. And for example, there has been 15 different pairs of signatures for 1963 1 Markka banknote!
About the sigantures, though this page is in finnish, check out:
