It is worth whatever the silver content is. From my searches it appears it is 1 troy ounce of silver which at the time of writing is worth about $22. However, the price of silver fluctuates on a minute by minute basis.
In 1980 Liberty Lobby, a conservitive organization, decided to mint silver coins for their members. This was the year that high inflation and high unemployment caused many people to speculate that a second great depression was inevitable. In 1983 a Liberty Lobby Silver Eagle, one troy once of .999 fine silver, sold for $13.00. These purchased coins came with a guarrantee of a $9.00 redemption buy back if returned in mint condition regardless of the price spot silver.
The 1989 (and all other dates) One Dollar Silver Eagle coins are bullion coins that have 1 ounce of pure silver in them with a value that follows the market price of silver which changes by the minute and right now it's $17.34 per ounce. Because of that the worth of the coin is a little less than spot price at time of sale.
The 1989 American Silver Eagles were issued as Proof and Uncirculated. Today the proof coin has an average market value of $25.00, uncirculated is $23.00.
1.00
The only dollar coins issued in 1980 were made of cupro-nickel, not silver. They're only worth face value.
The US Mint did not issue any silver coins of any kind in 1980. If you have silver coins dated 1980, they are not US coins.
There is no such thing.
He is asking about a 1980 LIBERTY Silver Eagle. It is a bullion coin that predates (and was privately minted) the American Silver Eagle (1986). The confusion comes from the reverse having the inscription “One Silver Eagle” which many know to be synonymous with “one silver Dollar“. It is not legal tender and is worth its weight in silver and any premium you can squeeze out of a collector.
It is worth about $10 in good condition and about $20 in mint condition.
It's a Silver Eagle not a Liberty coin no US coin is called a Liberty. The coin is made from one ounce of silver and the value is whatever the spot price of silver is at time of sale. The value as of 8-28-11 is $41.50.
1 dollar
1980 would make it a Susan B. Anthony dollar, and it's still worth one dollar.
