http://goccf.com/t/329354&SearchTer...lver,quarterI'm in agreement with previous determinations of others, it's a sand casted copy, possibly done in 90% silver but it's light, so maybe it's a different alloy of silver. Maybe 40%? for 40% weight should be 5.75grams, very close to the clad planchet weight of 5.67 grams.
One thing is for sure, the surfaces, and the edge are fishy, and the weight is that of a plated clad quarter, which makes sense if someone didn't know a silver quarter weighed more than a clad quarter.
And really? Been popping in and out about this coin for 2 years and haven't ponied up the $100 to know for sure and keep coming back for opinions instead?

the picture you showed is definitely not that.
What I think you have is someone made a sand mold and melted down some silver and some filler metal and made this one you showed in the other thread from 2018.
