If by a more scientific method, you can investigate the specific gravity of each coin. A sterling silver coin will have a value around 10.3.
If by a more subjective test, ring test will work for experienced ears.
I am quite suspected both coins will have different weights; the coin has a weight of 28.28 grams must be silver. A Cu-Ni coin will have a lighter weight by same volume of material.
