Does anybody have any idea on what the shelf life of grass seed stored in the sealed, original bag is?
Thanks, Joel

The rule of thumb is two years.
If it is completely dry and not exposed to extreme temperatures, it will be good for at least a few thousand years.

That's not true. The germination rate of seed declines over time, which is why the date the lot was tested is important. Typical grass seeds can be stored a couple of years in a cool, dry place and still have acceptable germination rates. Anything over a year old, I'd do a test prior to use to make sure the germination rate is acceptable. Also, endophyte enhanced seed loses the endophyte protection in a much shorter time, less than a year.
they have found wheat seed in the ancient pyramids that sprouted and grew. ........... Hank

I used some dated year 2000 in an opened bag a couple weeks ago. It is now growing well.
