Look for help in identifying if items are legit and for direction on how to authentic

[TheCatenacc]

Hello everyone.

Long story short, my wife's step father passed away recently and apparently had been sitting on quite the baseball memorabilia collection. Story goes that he sold off most of it pre-pandemic for somewhere around 150-200K but hung on to a few things.

My wife went down (we live in Toronto and her family is in Oklahoma) shortly after and brought some stuff back but some of it is still down south. So I haven't seen it all in person.

Below you'll see some photos. There's a Mantle signed ball. Some other mantle signed cards. Babe Ruth/Lou Gehrig signed ball (the only one of the bunch im skeptical of bc of the ink). A Lou + Elanor Gehrig signed baseball. And a Joe DiMaggio signed jersey.

Unfortunately, i have no COAs at the moment. But he did get his stuff insured in the past. And there is listed values of 4 to 6 figures on some of them. Would an insurance company not validate before giving off the value?

Anyway, I'm hoping any of you can possibly help in identifying if they look legit or not and what is my best option for authenticating? JSA? PSA? Another auction house? Is there a way to do it in person? etc.
