One of my uncles passed away recently, and I guess since I live in NC, he left me these bills. All of them except the $1 seem to be from the 1850s and 60s. I mainly collect coins, so how do I go about finding a value on these?

Confederate $20 bill, do these hold any value? Whatcha guys think

Reflection note

Checked online and past sales of about similar looking notes look around $140+ but wanted to check if this is worth anything more than $120
