newbie trying to find info on HO train collection

Hello, I am new here, as well as to the train hobby. I apologize in advance if my questions are silly or quite ignorant. I am a car person, and know how newbies are treated in some of forums, so I can take it.

Recently, my grandparents passed away after a long wonderful life. They were both in their mid 90’s and died with in a year of eachother. My granfather had been an avid train collector. We are in the process of going thru his stuff, dating back to at least 1938. At least that seems to be the oldest issue of model railroader we can find. He must have every issue from 1938 on. All bound and organized. No one in the family is knowledgeable about the trains, nor has an interest in the hobby. There are tons of trains, tracks, switches, buildings, people, parts, etc. It is all HO scale. I can only imagine, being a collector of “other things” myself, that someone would love to have this stuff, and that it would be very useful to an avid collector.

I guess my question is what is the best thing for me to do? Are there people out there that value collections? What is the best way to find a good home for this lifelong collection. Today we found all the trains and moved them to one area of the garage. So, the stuff is accessable for picture taking etc. I am in greenwood,sc if there happens to be a board member that is nearby, that would be interested in taking a look. Should I should post this in a different place?

Any and all help would be greatly appreciated. I have great memories of watching his trains, and understand his passion, I just want make sure it goes somewhere where it can be appreciated. Thanks.
