This is a 1908 Barber Quarter that I dug Metal detecting the other day. No the coin was not cleaned it was in good soil 10in deep and I only rinsed in water then soaked in water. NO SOAP OR RUBBING. also a Mercury dime that looks like a hard strike? I don't know it just looks odd. Please tell me what you think.
U.S. minted coins can have a 15% rotation and be within the mint's specification of a normal strike. The degree of that rotation is the key to it's value and desirability. A coin with 20% adds a little extra to it's collectability, and 40% more; and so on. Get a protractor and you should be able to measure the rotation yourself.
Is it 15% or 15 degrees? Because 15% of 360 is a rotation of about 55 degrees, which is pretty significant. I thought that the unofficial mint tolerance was a rotation of about 15 degrees, though personally I don't find them to be particularly collectable until about 90 degrees or so.
