Thanks for your comments!
This coin has no wear that I can see. Luster is very strong with just a slight muting in the obverse fields which I attribute to (very) brief circulation. There is moderate chatter in the fields as noted but no serious hits. I don't see any hairlines or other evidence of cleaning. The consensus grade of AU-58 sounds right to me.
The coin came in a sealed flip with a "certificate" from Littleton Coin Company. They called it AU-50. Maybe I'll keep my eyes open for other pieces sourced from Littleton.
