Most of Finnish coins are on Numista.
There still are many that aren't. Not nearly as much as other coins, but still quite many.
Let's start with the patterns:

This is a list of all the missing pattern coins. (including the 75pen 1863)
The second one is the Turku coins. These are extremely rare old coins. Currently there are only two Turku coins.

and 8P 1453-1470

Some things that may be wrong:
- The 1917 issues (example: https://en.numista.com/catalogue/pieces10386.html ) were actually made during the time when the Russian provisional government ruled the country, but for example the 25 penniä coin was actually minted by the "reds" (communists) too.
-This coin may be another one of P.U. Helle's "numismatic scam money":
https://en.numista.com/catalogue/pieces78538.html
- A 20€ coin was minted in 2017
That is all, probably all Finnish coins found, not on Numista. If you would like to add a turku coin, ask me for more information. I know the diameters and the amount of silver in them.
