I have a Sacagawea dollar coin with no date. Is this possible?
It's indeed possible to have a Sacagawea without a date. They are nowadays treated as antiques and $1 Sacagawea can sell for $47. Visit your local antiques store for more evaluation and details.
check the edges, it's most likely after 2008-2009 when they were released
The date is in the rim of the coin
