messed up title, baseball withOUT COAs

I have a bunch of hand me down signed baseball from my grandpa. None of these have COAs unfortunatley. Some of the better autos are a Don Larsen(x2), one is dated the day he threw the perfect game in the World Series. The other nice one is a Sandy Koulfax. So I have two questions, how much does the value depreciate without a COA? and is there any way I can get COAs for these? I might already know this ones answers but never know.
Thanks guys. lmk what you think

There are authenticators that will authenticate your baseballs for a fee. PSA/DNA is a nice option although you can expect the Koufax to be pricey.
