No way to know without knowing all the details of their storage. That is what determines shelf life of most seeds. If frozen and never allowed to thaw they may still have some germination at 2 years. Personally with 3 year old seed that was NOT kept frozen I wouldn't waste the time or space but would rather invest in new. JMO

It was just kept inside - I keep testing it inside but mice keep finding it and digging it up and not eating it. it looks like it is starting to germinate but not positive.
