It's not a recent addition but it's something I bought pre-Covid when I was really active in the HA weeklies.
I didn't know growing up there were different Seal colors except for the Silver Certificate Blue.  Though sometimes the Light, Dark, and Normal Greens can be tough to differentiate.  This one is clearly Light Green.
I have to review what the different Greens stood for.

Here's a useful description listing:

Yep, like the old pumps with the number wheels that would not line up.

I'd put a FMV of between $150 and $200 on it. PMG decides what to put on the label, it would say BINARY or BINARY SERIAL NUMBER somewhere on the label, usually they put it on the front if there is room. You can pay extra for PMG to put a pedigree on the label like Jogarced Collection, or something like that, but that's about it.

Mismatched Serial Number or Stuck Digit. 
Nice find.

This was the first dollar bill I found that started me down the road of collecting currency.

Here are a couple "close calls" I found recently.

I found this a few months ago. I have looked around, but I can't find a similar one to compare it to.

Doesn't really add any value, especially if they are not in pristine condition. Definitely not worth having graded. 

None of the numbers have any added value and I personally wouldn't pay a premium for any of them but if I was going to pick one I'd go with the 30008000 note the others are all the same to me.

It's a little confusing but I believe PMG's definition of a Super Radar is a radar serial number with matching block letters, not that four or six of the middle digits are the same. In this sense PMG does recognize "True" radars as they are the same as super in their book. That's how I interpret it at any rate, might be worth asking PMG for clarification. 
Nice radar-repeater. 

Nice one GF. 
Small size NBN's in circulated condition can be had for decent prices, I've been exploring them a little bit, might be a good area of the marked to dabble in undisturbed for not a lot of $'s.  When I say circulated I'm talking in the 30-40 range with Quality paper, a 58 like that would bring a good price. Someone may want to try and crack it out if it looked good in hand.

Pretty rare if authentic. I'm having trouble matching up the President's sig, the cashier is Ernst H. Meyer. There are only two different sigs pair with Meyer's, Nieman which this is not, and A. R. Dolph, the sig on your doesn't appear to be either. Doesn't mean it's not real, just that it's not matching up with known records from what I can tell. If authentic it could go for a big number.

I've never submitted a coin or bill for grading.  I can only say it's a function of how much to get them graded AND what the likely value is.  At $15 each, sentimental value aside, if the bills aren't each worth $75, it's a waste IMO.
Check comparable note sales on GC or HA or Ebay (but use Ebay last ).

I'm not sure how the procedures for bill grading work -- I know for coins you just don't submit only one as you get screwed on the price.  So explore your options with PCGS (or their successor) and PMG (the leader).
If the bill is circulated -- a 50-58 grade -- then aside from sentimental reasons, there might not be a monetary reason to pay for it to be graded and holdered.  It might be worth $125 and it might cost you $40-$50 to grade/holder it, understand ?

The key is the grade, I think.  Are all 4 corners razor sharp...it looks like they might be a bit dulled.  I trust it's well-centered and no discolorations.
Too many de-merits and then your $100 bill might be worth $150 after spending $25 to grade it, that's what I mean.  But definitely get more opinions and tell us how the bill looks to you.  The higher the grade, the more likely it is to be worth it.

A binary $100 like yours that is PMG-67 might go for $200-$250.  It MIGHT be worth it to do so...you'd be protecting the bill...you'd also have an official grade....but it's not a huge windfall.
If it doesn't get a 65 or 66, I'm not sure it's worth it.
 

I don't recall what I paid for this and why I even bought it !!  
I remember at the time I didn't know about National Bank Notes...never knew that private banks names were on currency in the last 100 years or so (figured maybe after/during the chaos of the Civil War for a few years something like that may have existed).  So a bit intriuqued by them and I bought this one in decent grade.
FRB's and private banks both had the language attesting to treasury bonds on deposit.

Added today to my collection.
