/1/ I don't think it has anything to do with your descriptions and everything to do with lot sales. In a lot of 20, the best and worst really, really stand out. Causes buyer's remorse and thus bad feedback. "I paid fair prices for 20, 5 were really nice, but one was really, really ugly" becomes "Disappointing quality"
/2/ I like Kanga's rules.
Also - make sure that anything important is in the title and description. Assume somebody has a search setup for THAT coin... how do they find it? What would they be searching for? List it in the right category! Give the KM#. Are there alternative names, nicknames, whatever - make it easy to find and buy YOUR coin vs. the massive mess out there.
