Number all six Sun Yat-sen commemorative coins
If the group contains six pieces, assign identifiers A–F. Give each coin its own Sun portrait, commemorative wording, grain-wreath side, full circumference, weight and diameter; the group photograph establishes quantity only.
Star positions, strike, cleaning and rim condition may differ across the six. Transcribe each visible design and inscription before separating patina, weak detail, wipe marks, altered edges or former jewellery work.
Match sleeves, labels and provenance to A–F. Leave any variety not supported by photographs open, and do not clean or file the coins to obtain a sharper image.
Build six individual coin descriptions
Read the visible year, denomination, wording and principal designs before using weight or diameter. Reconcile every reading with the correct identifier.
Take complete faces with the full rim, then add located details of lettering, portrait, grain wreath, inner border and edge.
Photograph each edge separately
Use overlapping sections around the circumference. Preserve joints, altered rims, holes, solder and former mounting traces exactly as found.
Record patina and high-point wear before comparing soft detail, cleaning lines and unusually bright patches. Do not disturb any surface.
State the limits created by packaging
Old sleeves and provenance can be retained as background but cannot replace the inscriptions, designs, metal surface and edge of the individual coin.
Coins with the same familiar name may still carry different dates, mint features or condition. Sort visible differences before broader comparison.
Keep measurements attached to the surface views
Within the A–F group, each face, edge, weight and diameter must remain together. Do not let a sharp close-up from one piece stand in for another.
A grading holder contributes its label and grade, while the enclosed date, variety and surface still need independent checking.
What the six-coin enquiry should contain
For every coin, provide complete faces, circumference, original weight and diameter, followed by neutral and raking-light condition photographs.
Transcribe the sleeve or holder separately, then check its attribution against the numbered coin. Any mismatch should remain visible.
Locate wear, scratches, knocks and rim changes on an uncropped face before supplying details. A dramatic enlargement can otherwise distort scale.
Retain original photographs alongside improved angles and colour-neutral copies. The earlier view helps reveal lighting differences.
A specialist can compare all six confidently when identifiers A–F remain on every image, measurement and attachment, with unresolved details clearly stated.
