I had to satisfy an urge on Friday and buy a coin. Went to a coin shop that I don't get to very often. Got it home and weighed it. A clad planchet weighs 5.67 while a 40%silver weighs 5.75. It is heavy but still within tolerance of .22g. Post any unstruck planchets type 1 or type 2.
Here is a Photo of the 3rd side. Had to do a tissue test, because I thought the cladding looked more like silver than clad. Next to a 64D Washington.
Since that scale only goes to tenths, there is a wider margin for what the actual weight could be. I assume this is a clad quarter as the only 40% would be a 1976-S, the proof coins were handled more carefully and I don't see how a blank planchet would get through the inspections. A 40% silver wouldn't show copper on the rim. I think you need to weigh the coin on a more delicate well calibrated scale, to get a more accurate weight. But I see copper on the edge.
Here some Blank Type 1 and Type 2 I have sorted.. I know I will get a question on this item 50C, 25C, 10C, 5C and 1C
My scale has a plus minus .03, never fails and hardly ever have to calibrate it. 5.77g is still on the heavy side.
The photo of the 3rd side (Post #2) clearly shows a copper core, so it can't be the only 40% quarter (1976-S proof). When they do the 40% its not sandwiched in layers, the metals are mixed together and the silver color takes over the copper color.
I mean yes the obverse and reverse layer is a sandwich with the core inside. But they mix the 40% silver with the copper for the core and the appearance is a whitish gray. A copper core is a basic clad. I agree it's a little heavy.
Odd that the tissue check with a silver coin seems to show the blank is silver (but that test isn't alway conclusive), while the edge photo shows it is a clad blank with a copper middle. Guess I'd vote for it being a clad blank.
I have already labeled it as a clad quarter planchet. You can't argue with the copper core present. It was just odd seeing it with such a white looking cladding. The above dime photos white but when I did the tissue test. Type ll blank left and a clad dime on the right.
