The 1980-P Sacagawea Dollar is really common in circulated grades and even up to MS64 grades that many of these coins can be found in circulation. In MS65 condition it is a little more difficult to find in circulation but with enough searching some can be found. In MS66 they are still somewhat common with possibly thousands still available with most of them being raw. In MS67 condition they become scarce with possibly less than 500 available. In MS68 condition they are almost unknown with less than a dozen known and with none being in higher condition.
