Help with possible value?

Hello, I know a little too nothing about Bank Notes as I have put all my time and resources into Numismatics.  But my grandfather passed recently and in his coin collection he left to me, He also had quite a few different types of paper currency from different countries. Here are two that got my attention and we’re at the top of the pile.   Any information would be greatly appreciated, thank you Much!

The red arrows are from a Photoshop program just so I could point out things that caught my interest. 
 

this other one is a two dollar bill which I have quite a few of, but I don’t have any with red ink or a red stamp where the number two is spelled out?

Your P-422 1928 Federal Reserve $20 note has # (numbers) is a Green Seal and the #10 indicates it came from the Kansas City FR bank. It has the Tate Mellon signatures. These were the first notes issued for 1928 (I believe) & are considered tougher/more desirable than the notes with the letters (indicating Reserve Bank issue). 

The value of any note is connected to its condition. Unfortunately, your scan looks more like a scan of a photocopy than an actual note (due to the high contrast/lack of grey scale = lack of detail). A quick way to get a ballpark figure would be to take it into a LCS dealer & simply ask (than double what he says) or wait for a reply here.  You can also use the P-422 code & search past sales of notes in F-VF (I'm guessing) on eBay or other auction houses.  You could also post a better image of the note on the Paper Money Forum or some other US-based site (I'm sure you'll get a quick reply). There are tough Federal Reserve banks & easy FR bank (#) & this info on your variety is beyond me.

The 1963 “United States” $2.00 Red Seal is a pretty common note (I even have one of these!) Just for comparison, your 1928 $20 has a Numista Rarity Index (NRI in the 70's pretty high) while the 1963 Two Dollar note has a NRI of 15 (pretty low & many collectors have one). It would be worth about $20 in perfect UNC condition. 

Just one word of advice, for future enquiries: try to get a good scan of both sides of the note (or photos). A photo with side lighting helps too.  You might want to try the Banknote Museum to ID what you have too before registering your note in your Numista account.  One note per enquiry will also help.

Good luck!

Thank you so much for all your advice, and I will take better photos and upload them.  Also, how do you get a Numista Rarity Index(NRI) # for an Item???

-You're welcome.

I hope I did not open up a pandora's box!  Use the link for the $2.00 I provided and scroll down below the pricing table. You should see “Get this banknote” title with a list of “Members from this site want to exchange it:” 

Point your cursor over the ? icon and it will explain how the NRI is calculated (based on the # of collectors who own it & wish to swap it). It should really be used with a grain of salt (not every collector enters their notes/coins here on Numista) but it may give a very general idea on how easy the note is to come by (low #) &/or how tough it may be to source (high #). There is the same function for coins too.
