Has any one had any working experience with a mobile phone app identified as Coin Snap? I observed it in use this past weekend at our club coinshow for the first time. Would like some views if anyone has tried out it. It is an app for grading coins. https://financefeeds.com/under-70-or-over-100-dollars-octa-broker-analyzes-oil-market-under-the-tension-in-the-middle-east/
