Ephemera collecting, raw vs graded - the future?

Hello, it has been awhile since I posted here. I've been quite active on the sports card / memorabilia forums of late. Recently there has been a lot of discussion there about the future of collecting sports cards, photos, and other ephemera in raw condition vs graded condition (PSA, etc.). The reasons why people are buying more graded sports items is rather obvious. But I was just wondering how others feel about this in relation to non- sport ephemera, raw vs graded? For instance, can I assume that most people in the future will only be buying non-sport ephemera, graded by someone like PSA or some other 3rd party grader? Except for maybe lower condition items? As an example, I have some vintage Hollywood photos I've been selling on eBay and I recently had a buyer ask me if I had any that were graded. I get this question often enough when selling sports cards, but rarely when selling non-sports photos, magazines & other ephemera. I am/was mostly a collector of raw ephemera and I sell pieces of my collection as my collecting interests change over the years. The selling helps fund my newer collecting habits. As I get older though, and begin to think about a future of selling a collection, to down size for example, I wonder what it's going to be like to try to sell raw collectibles to a crowd of collectors that want to buy graded items only. And I know the grading companies already charge some enormous grading fees. Anyway, I just thought I'd ask here how other ephemera and photo collectors feel about the future of collecting raw vs graded items? And the future of selling a raw collection when the time comes? Just wondering. Thank you.

 

is there a set of standards to grade photo's and ephemera ?
are there companies that specialize in that sort of thing..?
Comic books , well yes of course....... but other stuff as well?
