This has been the same for years on
ebay.
one thing sells stupid cheap and the next seemingly identical one goes through the roof.
Things you want to look for IMHO ,pictures, starting price, pictures, description, pictures, reserve, and did I mention pictures.
I always use plenty of pictures front, back, side, top, bottom, and a few more after that.
I also describe the item sometimes to an absolute fault, but I get bids better than the standard, say, 1909 penny.(and left at that alone)
I never place a reserve on anything. (period, end of sentence)
I either start it at what I want or 99 cents. If you can't afford to let it go for the starting bid, it shouldn't be up. If I go into an auction and see a reserve, I automatically hit the back button and ignore the auction (that's just me though)
I don't think it would be a "false" bottom if some people would look into literally "selling" their piece a bit more than here it is bid on it
