unless your friend is willing to sell each record individually on ebay - the only way to get anything close to what they're truly worth - you are likely to get pennies on the dollar, value-wise. your best bet is to find a trusted friend (or friend of a friend) to go through the collection to get some idea what, if anything, is valuable, and then sell those on ebay. classical vinyl (I'm not too knowledgeable about musicals) generally does not sell for much; in fact, your friend might even be shocked to find that the local college/university will refuse them even as a donation. the catch is that some classical is very valuable, and not necessarily because it's 'audiophile' (i.e. RCA living presence with the 'shaded dog' labels) - some records are highly sought-after because of the performer. tell your friend to do careful research before acting!
