Should I Open These?

I don't think you should open them.

Leave them alone, the rust is holding the car together packaging is most of the value.

It sets the coin aside from any other one like it not in the packaging. You know how those old men get at auctions. They think this is like finding a needle in the hay stack

Old saying is to leave well enough alone.
You have nothing to gain by opening them so don't.

i would like the packaging, but thats just me.

I think those are just littelton packaging so I don't think it would add any value to the coins at all. I have some ASE's that have packaging around them just like that (with different inserts) and that is why I think the packaging came from the littleton coin company and it will probably say that somewhere on the insert. This packaging adds absolutely no value to the coin so if you would like to take them out, I say by all means do it because those packages are bulky and take allot of unneeded space when storing the coins. I took all the ASE's I had (I think about 15 of them) out of their littletonm holders also

As was mentioned, there is a bit of neat info there. Leaving them in is what I would do as well.

The only way I'd pop them out is if one of the following two conditions needed meeting:

1. I was so low on storage space that this would get me some more.
2. I was going to put them in a display/album that would showcase them in a way that I liked better.

If neither were satisfied, then I'd keep them as is. Also, if you'd ever sell, I can see someone (who isn't as into the coin scene) maybe wanting to buy them more because they'd seem "more valid" (whatever that means) in a case than not in a case but that's about it.
