Jaime Hernandez: The 2002-P Uncirculated Sacagawea Dollar was only sold to collectors by the U.S. Mint in bags, rolls and in Mint Sets from that year. Because of this, the coins took a huge decline in mintage from the previous year. The mintage for this date and mint mark was under four million. Compare this mintage to the previous year when the Philadelphia Mint struck over 60 million.
The 2001-P Uncirculated Sacagawea Dollar had a much lower mintage than the previous year due to lack of coins being used in circulation. The coins were just not popular and most banks had more than enough coins to supply for commerce.
Bags: The U.S. Mint began selling the 2002-P Uncirculated Sacagawea Dollar in bags on April 29, 2002. Each bag contained a total of 2000 coins. Each bag containing 2000 coins had a price of $2,190 if purchased directly from the U.S. Mint.
Rolls: The Mint also sold the coins in rolls of 25 coins each. The price for each roll was set at $35.50 if purchased directly from the U.S. Mint.
Mint Sets: The 2002 Mint Set went on sale on June 12, 2002. Each Mint Set was sold for a price of $14.95 each if purchased directly from the U.S. Mint. Each Mint Set had an example of every circulating coin for that year from the Philadelphia and Denver Mints. Additionally, it also had the Uncirculated 2001-P and D Sacagawea Dollars even though they did not go into circulation.
