How much is a one dollar 1881 coin worth US?

Answer 1

First you need to check the back, above the "DO" in DOLLAR, for a mintmark. There may be a small "O", "S", or "CC" there. There may also be nothing there.

In average circulated condition, with a "CC" mintmark, it's worth $80-$100. With any other (or no) mintmark, it's worth $8-$10

In almost uncirculated condition, with a "CC" mintmark, it's worth about $200. With any other (or no) mintmark, it's worth about $15

An uncirculated coin will be worth about $400 with a "CC" mintmark, $40 with an "O" mintmark, or $20 with an "S" (or no) mintmark.
