There's nothing called a "commerative" coin. There are COMMEMORATIVE coins, but an coin from 1985 is unlikely to commemorate any major bicentennial. Special coins were minted in 1976 for the 200th anniversary of independence, and others were minted in 1989 for the 200th anniversary of the Constitution.
One way to know a coin is not silver is to check it with a magnet. If the magnet sticks to the coin, it is not silver. If the magnet does not stick, it still might not be silver. You can test it, but to do that you need a test kit.
Current value of a 1990 Eisenhower Centennial dollar is $23.00-$25.00.

The silver content of any coin with .500 fine silver is 50%. The silver will be alloyed with other metals, possibly copper and nickel, and maybe a few other metals. The actual weight of the silver used would depend on what other metals were used and in what ratios.
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.
