Uncle Passed away many years ago and my aunt wants to get rid of his collection. What to do?

My uncle passed away almost 20 years ago, he was a big NY fan. Mainly NYR, NYY stuff be he collected everything. My aunt is not looking for full value for anything she just wants to sell it for something so it wasn’t a complete waste.

I was wondering how I should help her sell it, Maybe reach out to Goldin Auctions or something? She really just wants to get rid of everything but there is so many values items here I’m a bit overwhelmed. If anyone has any recommendations please let me know.

Here are only some of the cards I pulled out. There’s still so much other great stuff.
