Totally sucks for a professional.Will not be specific on a search.If you type in one ounce silver round.It will pull up grams,half ounce,1/4 ounce it will even show you your gradmas butt.Search engine for ebay is wretched,anybody who says different is happy seeing everything on ebay that they want to show you.Not specific in the search,will not allow you to exclude words for the search.Wastes gobbs of time scrolling.
