I recently inherited an old dime collection, and wanted to know if this rainbow-like corrosion will cause these dimes to have low value. Is this something that usually appears on old dimes such as these? Would these coins be considered "junk silver"? I would like to know if these dimes would be worth putting time into putting them into cardboard flips
Just to let you know, these coins had been in a Whitman brand coin folder from about 1965. Funny, the clad ones did not corrode like the silver ones.

Yes, they are very collectable. Some collectors even prefer the toning over untoned coins. Whatever you do, don't clean them. That will lower the value faster than anything.
I have had my experience with cleaning coins. When I was a young kid, I used to try anything on these four wheat pennies. I would use bleach, vinegar, alcohol; anything I could get my hands on. Nowadays, I don't even talk over my coin!

True, but it's a personal thing. I'm an old school collector and I prefer my uncirculated coins be "blast white". It comes under the category of "eye appeal".
Yes, those dimes would be considered "junk silver" as their value is solely derived from the silver spot price, i.e. they would not have a numismatic premium.
