Probably good enough. Do a germination test in a flower pot. If you really
want to be obsessive, count the seeds, space them far enough apart to spot
each sprout, and count the sprouts. The bag itself may list a minimum
germination rate for comparison purposes. Whether the result is acceptable
to you depends on whether you're doing a large area that's crucial, or just
a little patching.

Thats what was said at the masters class last year. The theory behind
behind this (as told to me) is that with age the germ inside dries out and
thus replaced with air. Hence when placed in water it will float. I've
tried this on my own and found this observation to be true.
Please, if I'm incorrect, feel free to enlighten me with the correct
information. "Just cuz" will not suffice.........
If the seed has been exposed to high temperatures and high humidity
(think a nice warm garage in Houston), it'll still be dead or have
vastly reduced viability, but moist enough to sink. Conversely, a well-dried
but viable seed (perhaps freshly harvested from a well-dried plant) may float.
There are a number of ways of quick-checking viability, including such
things as tetrazolium tests, but the best method at home remains just
trying to germinate the seed.
My landlord just threw down seed that was 5-10 years old from the
basement and weeks later he's got a decent amount of grass. We weren't
sure whether it had a lower germination or whether the seed simply
washed down the hill some.
