It is a vintage cherry numpad. with that price we can get a new cherry doubleshot keyboard. The ebay sellers have become bolder and bolder. Get any crap and put a high enough price, if sells good laugh to the bank else drop price by 10%. Rinse and repeat.
Price very high, then drop 10% per week, is the best way to ensure that you get the maximum price for your item, unless it happens to spark a bidding war.
ebay wants you to start low in order for buyers to have a shot at bargains, but if you are a seller, you need a totally different mindset.
