Have had these for a while but unsure how long. Figure I’d keep them after noticing they’re old bills. One significantly older than the other I suppose. What says you?

Never paid attention to the serials until this subreddit kept popping up. Thought it was neat, shame about the creases. Got in my change at my local social club.

I looked on amazon for sleeves but they seem to only be sized for “normal sized” USD, this is larger like a business check.

Great grandfather passed away in 2001. These have been in a safe in a closet since then. I have no knowledge of collecting any currencies. I'm currently still going through all of his coins and I've been using coinsnap to track and identify his collection just for a general idea. This has all happened very recently and has gotten me totally interested in numismatics. Ive taken photos of fronts and backs of all paper currencies I've found in his collection and would appreciate any info or knowledge maybe there's something special or rare in this part of his collection that is just cool for collecting or offers a higher premium than expected. Maybe something worth grading or getting looked at by Ics. I've google searched every paper bill and didn't see anything stand out however i may have missed something or just to new to the hobby to know what I'm looking for.

My great uncle served on this ship and was in Tokyo Bay at the surrender. Obviously I wouldn’t sell this, but would like to know how common these are so I can insure it if needed.
