The 2009 Sacagawea dollar struck at Philadelphia had a mintage of 39,200,000 coins, and those coins normally have the date and mint mark on the edge , not the front. The Philadelphia coin uses a P mint mark on the edge, so a coin with no date or mint mark visible on the front is usually normal for 2009.

What that means

  • 2009-P mintage: 39,200,000.
  • No date on the front: expected, because the date was moved to the edge starting in 2009.
  • No mint mark on the front: also expected for the same reason.

Important detail

If your coin truly has no edge lettering at all , that can be a mint error rather than a normal Philadelphia issue. A normal 2009 Philadelphia Sacagawea dollar should still show the year, mint mark, and “E PLURIBUS UNUM” on the edge.
