The "dollar" denomination is of course artificial since these coins are sold as bullion pieces for their precious-metal value. The current price of silver is about $14 an ounce, so your coin is worth approximately that amount.
I don't know. Why does the sun rise?
Why does my heart keep beating?
All these questions were in an old love song.
The real question is how did I accidentally end up on the above persons account?
Maybe you can fix this for this dude who answers questions above.
Your coin is a 1 ounce bullion piece called a "silver eagle". Its value depends on the current price of an ounce of silver metal and the coin's quality. The lowest-quality pieces (MS60) sell at retail for about the same as an ounce of silver, while a higher-quality coin (e.g. MS65) might carry a premium of about 25%.
Silver eagles are coins minted for collectors and investors, and aren't the same as the silver dollars that were made up till 1935. The $1 denomination on a silver eagle is artificial.

One dollar.
If it's a circulation coin made out of nickel, it's only worth face value. If it's a silver proof, it could be worth about $15.
The US Mint did not produce any dollar coins dated 1985, look at the coin again and post new question.
