I actually find it far easier to sell anything except major stars raw. Primarily talking about Topps sets of the 50s/60s. Say a '61 maris PSA 4 goes for $100. If I get a nice Ex raw copy I can sell it for $90 all day and sometimes even more than a similar card that is graded.
So many people are building sets and so many cards are being graded I think it's annoying for set builders trying to find cards that fit their sets that should be in the $10-20 range just sitting on eBay in a psa 3 listed for $30 not moving. I know it is very annoying for me sometimes. Look at Greg Morris and this becomes very apparent how many people are looking for nice raw cards for their sets.
Not to mention the time it takes to sell. When I post a graded card it usually will take minimum, a day to sell. A nice raw copy equivalent can sell in minutes priced only 5%-10% less.
If I was a dealer I would absolutely be dealing in raw cards. Sure you can get 10% more graded, but turning over cards almost as fast as you get them certainly makes up for it to me.
Just my thoughts and opinion.
