Old Blueberry seeds. still working?

so i got these blueberry seeds as it clearly says in the title.

this is the deal. i bought some seed about a year ago on SALE so i guess they was allready quite old when i bought them right?
now a year after they even older.

the question is. how long until they unusable?
i´ve kept them in a dark fairly chilled place but i dont know if thats enough.

im sure they will crack open and grow but will the quality be as good as it used to?

anybody know?

yeh all seeds can be stored up to a suposed 10 years, however fossalised seeds have been germinated using gillabric acid... spelt wrong. but yeh you get the idea. ... store in cool DRY dark place for longest shelf life...

only one way to find out if they are still good (i imagine they are)! good luck!!

thanks for the replys guys
i think ima plant em right away ^^
