2/3 years, yah, not too old, you're right.
might as well have a go. see if they germinate. if germinated, then sprout 'em, then grow 'em till sexed. if male, rip 'em out. if female, grow out to see if quality harvest.
otherwise, why keep seeds?
i have sprouted 10 year old seeds, which produced.
I like the wet towel sandwich technique, but last time I put it in a zipped bag - which I thought was a brilliant idea everyone else knew, but me. anyhow, once the tap root splits the shell, you know its germinated - put that in the growing medium to expect it to sprout.
p.s. various theories, but one i thought might have work, is to gently cut/score/mark the old(er) seeds shell with a knife, before attempting to germinate - i say that, coz i wasn't sure if it worked or not on older seeds. maybe it was desperation....
