35mm Slides Coast Guard R&D Center

So this is interesting...before I post any for help...I have 9 slides, screen shots from a Coast Guard computer of ship missions and stuff, cargo ships and what not, 1 slide is a diagram of something...these date around 1985....I don't want to end up in jail as a spy...are these sellable?

 

Can we see the slide mounts? They might well be official issue, but I doubt anything over 30 years old is worth worrying about since any technology featured is long obsolete.

 

Here are a few...

 

Great shots of the images. Nothing classified there; they look like bits of a training program. If they're still government property you can't sell them. If they were surplused out you're good to go.

 

These are part of my Dad's belongings. He used to work for the R&D..
