If he is offering them for free and he will be hurt if you don't accept them, then, by all means, accept them and toss them after he moves.....if this is practical.
I work in a retirement community with all levels of care. Downsizing is really tough for anyone, but especially seniors. The mental toll is probably harder than the physical toll. If he is comforted that a) he is giving you something important to him and b) he can check them off of his moving/worry list, then you will be helping him a great deal.
Now, if you will be running into him often and he will be inquiring about them, and how great they are(were) and you will have to lie....that will be tough.
Good Luck.
