July 4, 2009 The mint mark for a 1922 Double Eagle is located on the obverse [heads] side of the coin just above the date. An "S" indicates the San Francisco mint and no mintmark at all indicates the Philidelphia mint. An MS62 PCGS graded coin minted in Philadelphia is valued at $1650. An MS62 PCGS graded coin minted at San Francisco is valued at $3400. It may be interesting to note that double eagles minted from 1907-1911 had 46 stars along the outer rim of the obverse side of the coin and those minted from 1912 to 1933 had 48 stars. The 2 additional stars were added because New Mexico and Arizona had been admited into the Union in January and February of 1912.
Be more specific no 1922 half dollars were struck

The coin is NOT an Silver Eagle (1986 to date) it's a PEACE dollar (1921-1935) and assuming the coin is circulated and has no mintmark, retail values are $16.00-$22.00 the 1922 coin is the highest mintage most common date of the series.
The 1922 is probably a peace dollar. It would have the word peace on the side with the eagle. The 1921 is probably a Morgan dollar. It has a Liberty head on one side and an eagle on the other. These are worth about $25-35 on average.
That design is known as a Peace dollar, and 1922 is by far the most common date. At current silver prices, it's worth about $23.
