Can you get money from a bank in Finland for markka coins?

Excuse me, I'm curious about something. I'm currently in Finland and I'm wondering if it's possible to withdraw Finnish markka coins from a bank here? I've heard that markka is no longer the official currency, but I'm interested in collecting some as a souvenir. Would a bank in Finland still have these coins available for withdrawal, or would I need to look for them elsewhere? Thank you for your help.
