NO !!!
Absolutely NOT!!!
Unless they are moldy, grimy, bug eaten, beetle bored up dust... there is no need to toss those beans.
I have had beans 4 5, sometimed 7 years old.
Are they as good as when I got them, oh hell no. are they good in a cup of coffee.... oh hell yes!! The tastes change, they don't necessarily go bad.
Once you roast them, yah they can go stale after a while, but the beans themselves, not so bad. remember when you roast it now, the ROAST is fresh again!
Give them a try I think you'll not be too disappointed.
Example, I do my Bubba's where I get rid of older beans Ive had sitting around a while, I constantly get people DM'ing me asking, oh man that was still soooo good, do you have any more, even only a pound or two?

that right there, should tell you something about alleged degradation
