Grading notes
Strike is part of the diagnosis.
Judge wear at the eagle breast, wing feathers, serpent, cactus, LIBERTAD band, and central rays only after accounting for weak strike, die wear, and adjustment marks.
Representative Republican issue study
1884 Zs JS Chopmarked 8 Reales
The photographed 1884 Zs JS carries merchant chopmarks from circulation. The underlying issue identity remains Zacatecas 1884 Zs JS; the chopmarks are a separate surface-history classification and are not erased or promoted as official Mexican counterstamps.
A mature diagnostic study selected from the complete matrix; neighbouring records stay matrix-only until they pass the same gate.

Attribution diagnostics
Read the complete identity before grade or price.
- Establish the host coin first: date, Zs, JS, eagle, cap, and fineness legend.
- Record each chopmark separately from graffiti, test cuts, and rim damage.
- Do not assume every punch is old or Asian; authenticity of marks requires its own examination.
