I know nothing about that dime, but the penny seems to be a slightly clipped planchet as Brendan said before. Good eye though for that clipped planchet!!!
note: I believe(correct me if I am wrong), if you put the edge of another regular penny up to the clipped portion of the clipped penny, if they match up perfectly, you got yourself a clipped planchet.
If the 1982 really is a no-P, it might be worth something like $40 (maybe less because it's corroded or damaged). It may just be damage though, it's hard to tell from the picture.
The cent is a small but genuine incomplete planchet. Worth a few bucks (though it can be hard to find somebody interested in smaller clips.)
