Message:: [QUOTE="Pete Apple, post: 3548059, member: 103982"]My point is:1) 40% Silver DOES have a copper core composed of about 4/5 copper --- it was stated earlier in this thread that[QUOTE="...There's no copper core in the 40% halves."[/QUOTE] Therefore the reason that a core is not visible is not because it doesn't exist, as stated earlier in this thread. The information I provided earlier in this thread documents this. My source for that information is: United States Patent Office 3,466,157 Patented Sept. 9, 1969 COMPOSITE METAL CONTAINING COPPER FOR CONAGE PURPOSES Philip B. Neisser, Alexandria, Va., and Morris V. Boley, Bethesda, Md., assignors to the United States of America as represented by the Department of the Treasury Filed Oct. 22, 1965, Ser. No. 502,738 Int, C. B23p 3/20 U.S. C, 29-199 13 Claims Filed Oct. 22, 1965 2) That the core of a clad coin frequently does not appear on the edge because of the action of a dull blanking punch. My source for that information “The edge of any clad planchet will show asymmetrical exposure of the copper core caused by smearing of the bottom clad layer as the blank is pushed through the coin metal strip by the blanking punch.” – Mike Diamond (CW 6/10/2019 pg. 42). Now if the blanking punch is somewhat dull, no copper core will be left exposed on the edge of the coin. also a source:Ken Potter “The amount of copper that shows [on the edge of a clad coin] is dependent upon how much of the outer cladding is pulled over the copper core when the planchet is sheared out of the strip. A dull punch and/or button (the hole) will pull more than a sharp punch. Sometimes the shear pulls more than other times and almost completely covers the copper core.” [/QUOTE]
