There is extremely little copper or Bronze. I am not sure what the used and the rest is a silver. I know they made Clad but is that how they made them? Looks like a %90 silver coin if it was. By the way I am totally aware that in 1964 they STOPPED making them.
if you are talking about a coin that you have, please post pics of the edge and obverse. if there is any copper on the edge AT ALL, then it is not silver.
Just a regular 1966 quarter in really bad shape. Looks like a perfect candidate for the nearest vending machine.

Agreed...the copper is clearly visible. It's important to know that clad coins will occasionally not show any copper on the rim at all. That just happens sometimes...so he rim is not a good diagnostic of coin composition. Weighing the coin is the only way to know for sure if you don't see copper. However, if any copper is visible it is clad, it's impossible for copper to be visible in a 90% silver coin because the silver is alloyed with the copper.
There is no way you, or anyone, could say that with 100% certainty from the blurry scans of the OP's coin.
Tristen, its pretty common people post here about 1965-1969 quarters thinking they are silver. The reason is that clad coinage was new, so metal in the strip was not as uniform as today. Also, they struck in higher relief then so the coins look "different" than today. The only way to tell really is to weigh it. Some of these have no trace of copper on the edges at all, but 99.99999% of them are still not silver. Hope that helps. Chris
It's really not all that bad. They made 821 million 1966 quarters and this one is in the top 275 million or so. More than half are already gone completely and about a third of them are culls like this one. But the wear is slightly less than average. Obviously it isn't collectible in this grade but most people would be surprised how difficult it has become to find a nice attractive and well made VF's of this date. In ten years nice F's will be tough. In 25 years this example will be almost decent.
It's just as well since in 25 years this thing will still be junky and it will take about twenty five of them to buy a candy bar. I'd save nice VF's except I can find nice gemmy ones for not much more than a quarter.
