Assuming that the coin does not have a different metal encased, you could measure its electrical resistance.
Or you could find its density.
MoreActually, no coin is strictly pure silver. The refining process can't produce 100% silver, although high-end techniques can come within 0.1%. That level of purity is only available in special bullion coins sold to collectors and investors. These items almost always have their purity level ("fineness") either on the coin's packaging or struck into the design itself.Silver that's more than .925 fine (92.5% pure) is too soft to put up with circulation wear. When silver coins were issued they were alloyed with copper to harden the metal against wear. Britain used .925 file (92.5% pure) silver in some coins prior to 1920. The US used .900 (90%) silver up till 1964, while Canada used .800 silver till 1967 and .500 for a while after that. However once silver prices were completely deregulated in the late 1960s countries worldwide switched to non-precious metals like cupronickel, steel, and so on.

How can you determine a coin is not pure silver?
By putting it in hot water for a week
How can you determine if a coin is pure silver?
No coin is 100% pure silver as 100% silver does not exist, the refining proces does not produce 100% metals. The easiest way to determine silver content is to look up the coin in an appropriate numismatic reference source. which will display metal content and weight for the specific coin you are referencing along with many other details. US collectible and bullion coins are 99.9% pure US circulating coins used to have silver content ranging from 85-97.5% but now are mostly copper with silver cladding.
Is a pure silver coin an element?
Silver is element number 47 -- Ag. A pure silver coin contains the element silver, but the coin itself is not an element.
How can you determine that a coin is not pure silver using density?
Find a caliper and a good scale. Divide the weight in grams by the volume in cubic centimeters. Pure silver has a density of 10.49 g/cm3
Is a pure silver coin heterogenous or homogenous?
It would be homogenous.

How can you determine a coin is not pure silver if you know the mass and volume of the coin?
Divide the mass by the volume to calculate its density. If its density isn't the same as an equal amount of pure silver, the coin has some other metal in it.The density test can be fooled if the coin was adulterated with other metals that average out to the same density as silver, however.
