What to record for every coin you own
Whether you keep a notebook, a spreadsheet, or an app, the fields are the same. A record that misses any of these will eventually cost you time or money:
- Identity: country, denomination, year, mintmark, variety (e.g., 1881-S Morgan dollar)
- Grade: your estimated grade, or the certification number if slabbed (PCGS/NGC)
- Composition and metal weight: matters enormously for silver and gold coins, where melt is the floor value
- Purchase details: date, price, seller — establishes cost basis and provenance
- Location: which album, box, safe, or slot the coin physically sits in
- Photo: one shot each side; enough to identify and document condition
That last bullet is the one everyone skips and everyone regrets. When an insurance claim or an estate appraisal needs proof of condition, your photos are the evidence.
Physical organization
- Keep storage inert: mylar flips, cardboard holders with mylar windows, or brand-name albums.
- Number your locations and use the same numbering in your records — "Box 3, row 2, slot 14" beats "somewhere in the den."
- Separate precious-metal stack items (rounds, bars, junk silver) from collector coins. They value differently: one pile is priced by the ounce, the other by grade and rarity.
Why the notebook-vs-spreadsheet debate ends badly either way
Notebooks die in house fires and cannot total anything. Spreadsheets total fine but rot: duplicate rows, no photos, no idea which pile of coins the row refers to, and melt values that were true when silver was half the price. Both approaches share a deeper problem — the record is disconnected from the coin and from the metal price, so it is always a little out of date.
The test of a good system is boring: can you, in one minute, produce an accurate total value of your collection at today's silver and gold prices, with proof of what you own? If the answer involves an afternoon of spreadsheet archaeology, the system has already failed at the one job it exists for.
