Watch List notes:

Guanajuato, Mexico, 1 peso, 1866, Maximilian, encapsulated NGC AU 55, rare mint. KM-388. Deep rainbow toning with lots of blue-green on reverse and red-orange on obverse, very light wear on highest points but otherwise rather choice and much rarer (one-year type) than the usual Mexico City issue. (Estimate: $2000 - 3000)
