Hello! That's a great question, as the 1976 Eisenhower dollar is a very popular coin. Its value really depends on which specific version you have, because they were made in two different metal compositions.
First, there's the common version made for circulation, which is a copper-nickel clad coin. These look like a very large quarter and have a copper-colored stripe on the edge. If you found one of these in your change, it's generally worth only its face value of one dollar. If it's in pristine, uncirculated condition, it might be worth a few dollars to a collector.
The more valuable version is the 40% silver Bicentennial dollar that was made specifically for collectors. These were struck at the San Francisco Mint and will have an "S" mint mark on the front, below Eisenhower's neck. A key way to identify them is by looking at the edge; the silver coin will have a solid silver-colored stripe, not the copper stripe seen on the clad version.
The value of these 40% silver coins is based on their silver content and their condition. Typically, an uncirculated 1976-S silver Eisenhower dollar is worth around $9 to $12. The proof version, which has a beautiful mirror-like finish and was sold in a special collector's case, is usually worth a little more, often in the $12 to $15 range. As price guides like Greysheet would indicate, exceptionally high-grade or professionally certified examples can be worth even more.
So, in short, check the edge of your coin and look for an "S" mint mark. If it's a silver one, it's worth significantly more than face value
