What adversely affects germination…?

Greetings, gardening friends!

Um...I'm not sure what tag or tags to assign to this post.

I just discovered a collection of seed packets (nothing extraordinary that you couldn't pick up at Lowe's, Home Depot's, or Wal-Mart's gardening centers: Ferry-Morse, Burpee, Northrup-King [are they, still?]---large commercial names) tucked away in a spot where I sometimes do place things on what is normally a temporary basis, but this time I forgot. They've been dry, but they've also been subjected to below freezing temperatures.

My question is: Very generally, how much will this have affected germination rates? What I'd been planning for this season coming up has been gourds, including loofah; runner beans; various cukes (Lemon, ; bush beans; asparagus beans; zucchini; leeks; turnips (Purple White Top Globe); parsley, flat-leaf; parsley, curley-leaf; several varieties of tomatoes (sorry, I've forgotten which ones and I'm away from home as I write this); chard; beets; peas. I've also got some seeds for broom corn; those are by Olds Seed Solutions (anyone? Tell me anything at all about this company?) And I have bunches of seeds for flowers, about which I'm not terribly concerned at the moment.
I'm willing to give them a shot; I'd hate to just assume that having had a literal freezing experience would have totally destroyed the seeds and so replaced them unnecessarily.

So...try them? Toss them?

Thanks.
