Also please note that ALL U.S. coins bear the motto "E Pluribus Unum" ("From many, one") so this is not a distinguishing characteristic of a coin. The denomination, date, mint mark, and condition are the most helpful characteristics to start with.
It's a very common Morgan dollar with values of $17.00-$26.00 for circulated coins
E Pluribus Unum is on every American coin 1926=$20 1926D=$22 1926S=$21
This coin would only have bullion value of about $13.62 as of today.
Circulated coins are $17.00 to $30.00 and it's a Morgan dollar not an E PLURIBUS UNUM coin.
circulated = $15 uncirculated = $30
Approximately how much is a 1929 silver dollar
There was no US silver dollar minted in 1950. If you mean a half dollar, it would be worth at least its value in silver which as of writing is about $7.70 but it would be worth more in better condition. As with all old coins, cleaning harms the value.
This would be the 1972 Silver Eisenhower dollar variety from the San Francisco Mint. In uncirculated condition, it would be worth about $8 and if you have a Proof coin, it would be worth about $9.30.
The 1776-1976 Eisenhower Dollar is just worth a dollar.
That's a bicentennial dollar coin, and it's still worth one dollar. The exception would be if the coin has an S mint mark and is made of 40% silver. These coins were specially struck for collectors and sold in individual packages. They can be worth $5 to $10 depending on quality.
1980 would make it a Susan B. Anthony dollar, and it's still worth one dollar.
It's a common coin, still worth one dollar.
