Ah, the 1972 Eisenhower dollar! A coin that has caused more confusion than a chameleon in a bag of Skittles. While the provided search snippets offer a lovely glimpse into the world of website navigation and free shipping deals, they're a bit light on the actual details. So let's talk turkey, or rather, eagle on the moon.
The most important question you need to ask is not "what is it worth?" but "is it actually silver?" Most 1972 "Ike" dollars are about as silver as a tin can. The ones minted for everyday circulation in Philadelphia (no mint mark) and Denver (a 'D' mint mark) are made of a copper-nickel blend. In circulated condition, these are worth exactly one dollar. In pristine, uncirculated condition, they might fetch you a few bucks, enough to make you feel like you won a very, very small lottery.
However, if your coin bears a little 'S' mint mark for the San Francisco Mint, you can do a little happy dance. These were made for collectors and are 40% silver. Their value is tied to the ever-fluctuating price of silver, but you can generally expect them to be worth somewhere in the $8 to $15 range. This is the version that actually lives up to the "silver dollar" name.
To add a wrinkle, there are also some rare and valuable varieties of the 1972 Ike that get coin collectors all hot and bothered, particularly a specific type of the San Francisco proof coin that can be worth thousands. But spotting the subtle differences on the Earth's design on the back requires a good eye and a bit of luck. So, in short, your 1972 dollar is likely worth either its face value or the price of a decent lunch, with a slim but exciting chance it's something more.
