Stamp or Currency!

When I first saw this stamp among the others I received from Russia this is what crossed my mind. Is it a Stamp or a Currency?

Yes, it is a stamp! It was issued by Russia on 1 September 2008 to celebrate the 190th anniversary of Goznak.

Goznak is a Russian Federal Government-owned corporation responsible for the production of coins, bank notes and other security papers. Goznak was established on July 6th 1919. Goznak not only prints Russian money, but also prints banknotes of a few other foreign countries. Currently it is engaged in printing biometric passports for Russia.On 3rd of September 2008 Goznak celebrated its 190th anniversary.
