Sacagawea Dollar 2000 P Errors

Unless I'm mistaken, the 2000-P Sacagawea dollar has a plain edge. Although, I do agree with potential edge-lettering effects on later coins that have it. From what I've read, it is added post-strike in a process similar to upsetting and for business strikes only.

This looks more like an effect from a slightly misaligned die or off-center strike.

Can you post full-coin pics of both sides (obverse/reverse)?

Thanks spruett001. I think you are right on the mis-aligned die mark theory since it continues concentrically around 75% of the outer edge of one coin and 33% on the other coin. I don't have the capability to photograph the whole coin at a magnification that shows the rings. I only saw them when examining all my 2000 P Sacagaweas for errors with my 10X magnifying glass. How can I find out? Do I take them to a place like a coin show and get someone there to look at them, or a coin collector shop? And, since both are pretty dirty, should I clean them, or leave them as is? Thank you for any insight you can offer!
