When you are shopping on eBay, it's helpful to look at all the pictures. The photo above was recently a gallery photo of a little lot of 45's on eBay with the title "Big Lot Misc. Vintage Records 45s." The description wasn't much more help in determining the contents of the collection. If fact, I only noticed it because the lot sold for $217. That seems pretty good for a $15 record tote full of 45s, until you look at all the pictures. Included with the lot was a Fe-Fi-Four Plus 2 on Lance. Condition, not noted, but in near mint that's a $500-1000 record. Which brings me to tip #2 for the day....if you're going to sell lots on eBay, invest in a price guide. For specific sizes/speeds of records, there are numerous Goldmine record price guides and if you're looking for a big all-in-one type guide, go with the Rockin' Records price guide. If you find one valuable record that you'd have otherwise put in a lot and sold for nothing, you'll have made your money back.
