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.
This coin has a eagle on one side and a double eagle on the other. On the side with the eagle head it has written American Eagle Bicentennial 1985 and on the side with the double eagle is written double eagle commemorative with stars and 200 years It appears to have a silver base with the eagle's done in gold. It is in a clear plastic case. Any ideas of worth?
The American Eagle Bicentennial quarter with the double eagle isn't overly valuable. In good condition, they can sell as high as $50 but no higher.

Bicentennial quarters are still worth exactly 25 cents each.

Bicentennial, not centennial. 1776-1976 is two hundred years. Bicentennial commemoratives have the Liberty Bell and moon in their design. Other dates have an image of the eagle landing on the moon. In circulated condition these coins are interesting curiosities but have no extra value. Uncirculated copper-nickel ones are worth about $2. Uncirculated 40% silver Bicentennial dollars are in the $7-8 range.
The US Mint did not produce this coin and it is probably the product of one of the private mints. Its actual value would be limited to the worth of the metals it contains.
Bicentennial quarters are still worth exactly 25 cents each.
