Identification help [resuelto]

Is this a banknote?

No, this is not an actual banknote. It's a share certificate issued by a Russian company called MMM. This company is known to have run a Ponzi scheme, a form of fraud designed to lure in investors (usually for a fee) and only pay the early ones, but with profits from said fee. You might be able to find your note/certificate under the Exonumia section.

Thank you

It's actually listed under Tokens
