Identify the Maple Leaf year and size first
Royal Canadian Mint information dates the series to 1979 and records later issues at .9999 fineness. Copy the subject coin’s year, value and inscriptions before using series-wide facts.
Keep one-ounce and fractional sizes separate. Published weight, diameter and fineness belong in an official-data section, not the measured-results section.
Micro-engraved maple leaves and radial lines were introduced on particular later issues; verify the exact year and size before expecting either feature.
Separate specifications from measurements
Cite the official source beside nominal dimensions and metal data. Photograph any actual reading with its tool, unit and packaging limitation.
Do not turn a boxed specification into an observed result when the sealed coin has not been measured.
Sort by year and visible edition
Retain complete obverse, reverse and edge views, including denomination, portrait, maple leaf and security positions supported for that issue.
Give each coin, capsule, certificate and receipt matching numbers so different sizes cannot exchange data.
Match packaging to the enclosed coin
Photograph seals, labels and serials without opening a stable package; control reflections through lighting rather than surface contact.
Map fingerprints, scratches, colour changes and contact marks as visible, never polishing or filtering them away.
Preserve the sealed state
Keep commemorative subject, metal specification and condition as three separate evidence groups.
Use direct review only when a concealed surface or conflicting package detail affects the conclusion.
Compare package data with the year-specific design
Reconcile nominal data, observed designs, package numbers and any measured values without allowing one field to substitute for another.
Describe each surface mark by side and position; ‘good condition’ does not allow a repeatable comparison.
Retain earlier readings when later equipment differs, recording the new setup and date.
Count every coin and linked document at handover, preserving unsupported claims as background only.
Leave the coin sealed and uncleaned unless a defined inspection need outweighs the packaging evidence.
