Values are:
No mint mark, "O", or "S" - about $17
"CC" mint mark - $100 if worn, $200+ with only moderate wear. Note that there are Morgan dollars and Trade dollars, but they're different coins. Trade dollars all have those words on the back. Plus, 1880 trade dollars were only issued in proof, so it's almost certain you have a Morgan dollar (the classic silver dollar most people think of)
Assuming the coin is circulated, the 1880-O Morgan dollar is common. The retail values are $36.00-$47.00 depending on condition. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched, used as jewelery or have been cleaned have far less value if any to a collector or dealer.
The Actual Silver Weight (ASW) is .77344oz of pure silver. All silver dollars (except Trade Dollars) from 1878 to 1935 contain the same amount of silver.
