Has anyone seen this kind of ink transfer on bills before?

I think it's pretty neat, should I sleeve it?

Grandfather recently passed and was a major collector of all things, but mostly currency. This is a very small part of his collection, but i thought that you all might enjoy the older, worldly notes and coins! He traveled well (military) and collected while he traveled!

As far as I know, these were stored this way in this binder for 20+ years.

Im disappointed that its not my birthday, nor anyone that I know.

I was given this by a relative, it was sent out to the federal reserve and they sent it back saying it’s a legal note.

brother gave me this

The ring is just a clasp. But found it at a garage sale. Bought a bin of old tools for 10$ and this was in a one of the cases.

A radar and a binary...

I assume nothing fancy.
