what exactly is this and how much is it worth? The Laika

This is a copy of the banknote issued by the manufacturer. I don't know if there is a market for it, how much is it worth?
 

I expressed myself wrongly, they are specimens, samples

These are print samples provided to potential customers to show what the company can provide in terms of print quality and security features.

ok thanks, what is the value of that and is there a market for these types of banknotes?

There is a market for everything (but it's probably smaller), I am not interested in exonumia so I have no idea.

Thank you
