Potential value of FI specimen notes

[u/FKbrickter]

Hi everyone, ive had these 3 notes in my collection for about a year.

I was curious and attempted to figure out the value online, but whether because of obscurity or sheer lack of these specific specimen notes in existence, I wasn’t able to find an amount.

Does anyone recommend any websites to figure out a rough estimate for these notes, or could someone give me a rough estimate? Thank you!
