These may be the only proofs or specimens left in private hands. The other reported Proof pair is believed to have been donated to Yale University and the only reported Specimen note is in the Banco de Mexico museum.

Condition: Face piece – UNC with what appears to be modifications made in denomination line below central vignette and upper left and right of Title where “No.” eventually appeared;
Back piece – UNC.

Each is original as used in production notes (i.e., neither is a color trial).
