Overall, I think Elizabeth offers some excellent advice. If it were me, I would go through your collection and pick whatever records you think are worth the most. Just put a few on ebay and see what happens. Use the results to help figure out how best to sell the rest of them.
LP collection
I inherited an extensive LP collection of early 50's first pressing classical and opera in stellar condition. Many are unplayed so they are not garage sale fodder. The question is what's the best way to sell them, and I don't want to do it one by one. Should I seperate them into small batches, by label, etc... Thanks in advance. Ron
