    You need to provide more information than a picture.
    Could be plated.
    How much does it weight? Do you have a gram scale?

    Silver weight - 6.25 Grams
    Clad weight - 5.67 Grams

    It's very important you get yourself a gram scale.

    One of the coolest quick checks I found for silver, I learned here on CT. It is not a scientifically definitive test but it works pretty dog-gonned good and I like to share it when I can. All you need is a single ply piece of tissue paper..... Take a known silver coin and a known clad coin and lay a single ply piece of tissue over them. The silver coin will always appear bright through the tissue. Almost as if it is lit up.... Again, this is not an end all test, but darned if it don't work pretty good.

    The weight of a Silver Clad Quarter, adjusted for tolerance, is too close to the weight of a Cupronickel Clad Quarter, adjusted for tolerance, to identify the type of cladding.

    Quarter 1947-1964 = 6.250 g +/- 0.194 g (900 Ag 100 Cu)

    Weight of Clad quarter 1965 – to present = 5.670 g +/- 0.227 g (75 Cu, 25 Ni on pure Cu)

    (1976 = 5.750 g +/- 0.200 g - 40% silver clad)

    A specific gravity test can tell. Specific Gravity Test. 90% Silver = SG 10.34; 40% Silver = SG 9.53 Cupro Nickel clad = SG 8.92 Copper Cent = SG 8.83; Zinc Cent = SG 7.17; Steel cent = 7.7

    Here are instructions about how to perform a specific gravity test:

    Another alternative to determine metal content is via an XRF Scan.

    Of course, it would be a real find to turn up a 1971 quarter struck on a 40% silver blank, since those weren't issued until 1975. :rolleyes:

    A gram scale will tell the metal weight and if you have a good ear and hearing you can tell that ring of a silver coin and the difference in the sound of a clad coin.

    Isn't that some sort of a wax treatment?

    I was going to say that I don't know what the current exchange rate is, but I don't have any plans to go to Bazil, so I probably wouldn't be interested.

    That is true for 40% silver quarters and cuppernickel clad quarters, it is not true for 90% silver quarters and cuppernickel clad quarters. The minimum weight for a silver quarter would be 6.06 grams, the maximum weight for a clad quarter is 5.9 grams so a gap of .16 grams between the tolerances.

    I'm going to try your trick I will let you know how it works out I keep going over this coin because the Finish looks a lot like silver the tarnishing is like that of a silver coin ..........the clad coins that I have seen do not tarnish like this they tend to look more dull ..but do to the weight that it gives what else can it be a Canadian quarter with the weight of 5.6? It has weird circle trought the whole obverse of coin..? Once I do my thurow research on it I will let you guys know my conclusion.

    Would be nice it weights same as bicentennial coin or Canadian 1940s quarter. Looks allot like silver also tarnished just like it. Not dull at all

    In your photos, it looks like it's the same color as all the other clad coins (except the edge, of course).

    If the surface checks out as silver, then it's plated. There's no way it could be the same size as a clad coin, composed as silver, and the same weight as a clad coin -- silver is denser. Yes, the weight is closer for 40% quarter planchets, but those didn't exist in 1971.

    A gram scale should settle it as far as being 90% silver.

    There were some 1965 quarters minted on 1964 silver planchets, as they were
    minting 1964 coins into 1966. There is also the rumor of 1 or 2 1966 on silver.
    But none after that. It's highly unlikely this is anything but a clad quarter.
    Did you weigh it? That will usually answer over 90% of the questions.
