I make these by hand from quarters from the 60's to the 90's 91% copper 9% nickel. pro's like EVH, Billy Gibbons and Brian May all used coin picks. I now know why. I find alternating picking and pinch harmonics with these coin picks is much easier with no drag. they're about the size of a jazz III. they take about 2 hours to make each. the cost is my labor. The Claton pick is a standard pick size.
Good tone starts in your hands and these picks sound awesome.
