Worn image coin comment.
Several times ive weighed batches of barely recognizeable 90% us silver along with good crisp 90% of equal value. about 10 face at a time.
do the experiment yourself and report here your results.
pick the worst non shaved of course, just used worn heavily
you will be surprised how close the 2 are.
the 71.5 vs 72.5 figures you see are about 1.38% apart
that is a normal alowance for wear.
most places will buy your worn at 71.5 toz/100face.
In my opinion you might look foolish to a vet or pro if you were weighing 90% instead of counting it but Im not sure what east coasters do.
the wear on the image is not all missing metal, some of it is just displaced , same with edge reeds to some extent.
do it yourself , maybe you will rest easier either way.
heck , sell of your worn stuff if you are woried and get all 1964 .
of course maybe some of you got a batch that is so far gone its a one in a million bag.
a refiner may buy large amounts by weight but you are going to miss soem deals if you nitpick 90%.
I expect other opinions , But heres mine anyway. worth what you paid.
