Normal weight of a clad quarter is 5.67g, so this is within tolerance.

There are also some errors of rolled thick planchets and rolled thin planchets, but these would typically be out of the tolerance range when you weigh them. The rolling mill takes ingots or bars of coin stock and flattens the metal to the desired thickness of the planchet's denomination but this is rarely discussed as few until recently weigh all their coins and the mint didnt care much about non silver or gold coins weight fluctuations as much. https://www.error-ref.com/rolled-thick-planchets/https://www.error-ref.com/rolled-thin-planchets/

I don't believe the mint produced 40% silver quarters until 1976.

Washington quarters Years containing 90% silver: 1932-1964 weight 6.25g. So its too light even with tolerance allowance to suggest that. Any United States quarters minted since 1965 is a clad coin that weighs 5.670 grams (0.200 ounces). This coin as mentioned is within tolerance to be within normal 1970 quarter weight. Quote: I don't believe the mint produced 40% silver quarters until 1976. This particular version you mention is the special 40% silver Mint Edition of the Bicentennial Quarter with S mint mark (1976-s). Proof silver coins with a mirror-like surface. In addition, A business strike silver uncirculated edition of this coin was also produced that does not have the mirror-like surface. The 1976-s weighs 5.75 grams and so if this were a 1976 quarter or 1977 perhaps it could be considered for an error since the weight is off, but as mentioned was not existing in 1970 so thats also not possible.

the side show normal clad quarter. 5.8 gr is on the Mint parameters. Nothing abnormal.

Easiest quick tell that it's not a silver quarter is when you see that brown ring on the reading. If you see that then it's a clad coin on any for any denomination and year.
Edit:for USA coinage, not all coins.
