What kind of radar note is this? and is it worth keeping

It’s not a radar or repeater.
Just kind of interesting...some will call it a binary.

 

It is interesting.

 

Yup, that is a nice $20 bill with a binary serial number. Those are highly sought after by fancy serial number collectors.

 

Thanks!

 

what would this be worth by any chance.

 

It maybe would sell for $30-40 on eBay.
At least $20.
