The trip to USA was a good one for me, I was able to pick up a lot of Dollar coins. I picked up the  Sacagawea dollar.

The Sacagawea dollar (also known as the "golden dollar") is a United States dollar coin that has been minted every year since 2000. These coins have a copper core clad by manganese brass, giving them a distinctive golden color.

The coin features an obverse by Glenna Goodacre.

The reverse design has varied, from 2000 to 2008 featuring an eagle design by Thomas D. Rogers. In 2009, the reverse of the Sacagawea dollar began changing yearly, with each design in the series depicting a different Native American accomplishment

Also picked up The Susan B. Anthony dollar of United States coin minted on 1979 both the P & D mint coins.

 

The Susan B. Anthony dollar is a United States coin minted from 1979 to 1981, and again in 1999.

It depicts women's suffrage campaigner Susan B. Anthony on a dollar coin.

It was the first circulating U.S. coin with the portrait of an actual woman rather than an allegorical female figure such as 'Liberty'.

The reverse depicts an eagle flying above the moon (with the Earth in the background), a design adapted from the Apollo 11 mission insignia that was also present on the previously issued Eisenhower Dollar. It was one of the most unpopular coins in American history

The 1979 Susan B. Anthony dollar coin was produced at 3 US Mint facilities; Philadelphia, Denver and San Francisco. The mint marks for this coin are located on the obverse [heads] side of the coin just above the right shoulder. The letter "D" indicates the coin was minted at Denver. A letter "S" indicates the coin was minted at San Francisco. The letter "P" indicates the coin was minted at Philadelphia. The 1979 Anthony dollar was the first coin to bear the mint mark "P" for the Philadelphia mint since 1945. Note that "FG" is not a mint mark, but the monogram of Frank Gasparro who designed the coin

Added to my Presidential $1 Coin collection. Thanks to Sivaguru for the help he provide in identification of the mint mark and also contributing to my collection. Thanks to Raghavendra and Anirban Dhar for helping me to complete my set of D mint of Presidential $1 Coin. Also picked up some coins to my friend collector Mr Syed Quiser, a very good coin collector, with old British Indian coins as his price winning collection. Anir is also a collector with some unique coins in his collection
