With popsike, don't just use the highest-ending result to price your auctions - do some research. Especially since you're a new seller, those outlier-high prices are not something you'll likely get for, say, a copy of Ayler's Bells (even if it is a first edition). Set your reserve just a bit lower and you might be surprised at what you get. Considering what you have, I'd be surprised if some of the rarer items go for "chump change" - they're good records and hard to find in nice condition, so let the bidders do the talking.
