This page covers Yuan Shikai silver dollars and Mexican Eagle dollars, with attention to their distinct varieties, edges and mint records. The two coin types come from different countries and monetary systems. They may share photography and measurement methods, but they must not be forced into one “provincial mint” framework.
Keep the two monetary systems separate
Check a Yuan Shikai dollar against Chinese denomination, date and die-variety records. Check a Mexican Eagle dollar against its Mexican mint mark, date and variety. Retain authoritative references for each system rather than borrowing names across them.
A shared physical-inspection checklist
- Photograph the obverse, reverse, edge and close details of lettering under the same light source.
- Record weight, diameter, thickness and the accuracy of each measuring tool. No single measurement establishes authenticity.
- Record patina, wear, cleaning marks, scratches, knocks, provenance and old storage labels.
Surface treatment boundaries
Do not polish, acid-clean or remove the patina. Online reference values are comparison aids only; wear, measuring error and historical die differences can affect readings. Higher-risk items still require physical inspection.
Frequently asked questions
Does a close weight establish authenticity?
No. Weight is only one piece of evidence and must be checked against the die variety, edge, metal, surface and provenance.
Can Yuan Shikai and Mexican Eagle dollars use the same variety classification?
No. They may share photography and measurement fields, but their historical mint records must remain separate.
Should either coin be cleaned before photography?
Not recommended. Cleaning alters the original surface; first, keep it as is and record it.
