Based on my personal experience and in talking with other Beatle collectors, I decided to detail out the top mistakes sellers make when attempting to sell Beatle vinyl on eBay. If I missed anything, please feel free to email me.

1. Not Showing Labels: By far the biggest mistake (and frankly the most annoying) a seller makes when selling Beatle records. The labels on Beatle records are of paramount importance to a collector. They are not all equal! Always show a large clear scan or picture of the record label.
2. Not Using Goldmine Grading System: Even if selling records is not your primary thing on eBay, take the time to learn the Goldmine grading system or tap someone who is versed in the standard to help you grade your records. Statements in descriptions like "it looks good to me" are a huge turn-off to potential buyers.
3. No Shipping & Handling in the Item Description: By not stating the S&H you are forcing the potential buyer to contact you. A major hassle (trust me on this one). State the S&H in your description or use the shipping calculator.
4. Overstating Shipping & Handling: You might as well add to your description in large bold print "I am looking to rip you off". I see listings all the time where the seller starts the opening price very low but has the S&H jacked up beyond any level of reason. The seller either ends up not selling the item or they sell the item for far less than if he/she had just charged a reasonable amount for shipping and handling. Set reasonable S&H levels and you will see more traffic and bidding come through on your item.
5. Descriptions That Go On and On: Make your description concise and to the point. No one wants to weed through run on sentences, personal opinions or the history behind Sgt Pepper. If a record is rare, cut to the chase and explain why without making the buyer rummage through paragraph after paragraph in order to glean the key points.
6. Minimal Description but Volumes of Seller Terms & Conditions: Most buyers will by-pass your item. The buyer perception? The seller is a hassle to deal with and his/her terms are more important than the item being sold. Avoid writing a contractual agreement. If you have special terms, net it out and devote more energy to the item you are trying to sell.
7. Reserves: Reserves should only be used for true highly collectible items. Most items with reserves never see the reserve met. Why? Because buyers don't want to play the guessing game. It's a time waster. If you are looking for a minimum price for your item then start the item at that price. If the item is truly worthy of your expectations, buyers will bid and you'll get your price.
8. Unresponsive Sellers: Be professional. If a buyer takes the time to write, the seller has an obligation to respond in a professional and timely manner. Even if the answer to the question is in the posted description, sellers needs to maintain a prefessional decorum. Not responding or snappy / curt  responses are un-necessary and  a turn-off.
9. Bad or No Pictures: "A picture is worth a thousand words" is how the old saying goes. There is no reason with today's cheap technology (digital cameras or scanners) to show blurry, fuzzy or worse no picture. Sub-standard or no pictures in your item description leaves the buyer with a perception of laziness and/or lack of expertise on the part of the seller.  Invest in a decent camera or scanner and make your item appealing to a potential buyer.
