I recently bought one at a local coin shop for $57.00, it was graded AU but it has such good luster and no scratches, marks or nicks that I can find so I think it may be a little higher grade.
It is: 1945-20 - 1925
It is my understanding that they were hand stamped without great care of location of design on underside. In any case the one I have is not quite upside down but very close.CorrectionUS coins were never hand-stamped. If you look at the front right-side up and the reverse is right-side up when you turn the coin from top to bottom, this is the normal orientation for US coins.
1925
The multiples of 275 (which are infinite) are all divisible by 275, including these: 275, 550, 825, 1100, 1375, 1650, 1925, 2200 . . .
M= 1000 C=100 x=10 v=5 if a smaller number comes infrontof a bigger one it is a -/ subtraction mcmxxv= 1000+ c from M (1000-100)=900+v(10)+x(10)+V(5)= 1925
The only U.S. "Stone Mountain" coin is a 1925 half dollar. Please look at the coin again and post new question.
Please check the back of the coin. It's a half dollar rather than a silver dollar. There's more information at the Related Question.
The coin is a 1925 Stone Mountain Memorial half dollar. Values for circulated examples are $35.00-$70.00. Mint-State are $90.00-$125.00 on average.
45 dollars in vf condition and xf

Current retail is $35 in VF condition, $45 in XF.
A 1925 Stone Mountain quarter is worth around $10 to $20 in circulated condition, and up to $200 or more in uncirculated condition. The value can vary depending on the coin's condition and any unique characteristics it may have.
All of the coins were struck at the Philadelphia Mint. So none of them will have a mintmark.
All grading takes into account the strength of the strike, the amount of wear on the coin and damage to the coin such as nicks and scratches.
Please check your coin again. The only half dollars minted in 1925 were commemorative Stone Mountain halves. In addition the image used from 1916 to 1947 was the Walking Liberty design. The Standing Liberty design was used on quarters minted from 1916 to 1930.
$13 to $18
No Liberty halves were struck in 1924-1926. Four different commemorative halves were struck that year, though; please post a new question with the coin's specific theme. Possibilities are Stone Mountain, California, Lexington, and Fort Vancouver
