Yeah, that will help.
There are big buyer type stores in NY, LA and Chicago, but they are going to need a rough list of high value records to determine if it is even worth their while (and of course, once you go down that rabbit hole, it's about particular pressings).
A local store, depending on where you are, may be an outlet but most stores, even the higher volume specialty places, are going to pay a fraction of retail.
The only way to maximize return is to retail them (giant PITA) or have someone do the work (cataloging, listing, shipping and handling payment/returns) and cut you a check. I unloaded thousands of records using a guy outside of NY--he came to my house, picked them up, did all the heavy lifting and sent me periodic payments. I trusted him implicitly, it was largely "found" money for me-- since many of the records I got rid of had been purchased decades before.
So, convenience v. maximizing return-- a common quandary, no?
