I am moving and want to sell about half my collection. A dealer is coming tomorrow to look at the lot. There are about 300 pieces total. 200 records are domestic US pressings from the 1970s, mostly classic rock, hard rock and prog. Think Led Zeppelin, King Crimson, Yes, Beatles, etc. The media range from VG to VG+, sleeves are pretty typical for that era. A few have water damage. 100 records are modern pressings and reissues, mostly indie rock and alternative. Bon Iver, Sufjan Stevens, Fleet Foxes etc. Media is all VG+ to M- and some have been opened but never played. How much should I ask for this? What price is fair for both me and the dealer?
