Catalog Your Coin Collection
A coin is identified by three things — denomination, year and mint mark — and priced by two more. TrophyShelf gives each of them a field, with a rarity scale that runs to Key date and a slot for a PCGS or NGC certification number. This guide shows how to record a Sheldon grade such as MS-65.
Three fields carry a coin
A coin is identified by less than most collectibles and priced by more. Denomination, year of minting and mint mark get you to a specific issue — a 1921 Morgan Dollar with a D is a Denver strike and a different coin from the same year out of Philadelphia, which carries no mark at all.
TrophyShelf gives the mint mark its own field rather than folding it into the name, which is the difference between a shelf you can search and a list you have to read.
What a coin records
The type is Coins — ๐ช in the picker, and the name box suggests 1921 Morgan Dollar, which tells you who wrote it. Seven fields of its own, plus the universal ones.
Which fields identify the coin?
- Denomination — free text, so 1 Rupee, 25 Cents and ยฃ2 all fit as written.
- Year of minting and Mint mark — together, the issue.
- Country of issue — a list of 197, which matters more for world coins than for anyone collecting one country deeply.
- Material / composition — gold, silver, copper, nickel, bimetallic or brass.
Why is the rarity scale worth using?
Because it is written in numismatics rather than in general collecting: Common, Uncommon, Scarce, Rare, Very rare and Key date.
Key date is the one that matters. It is not a step above “very rare” — it is a different claim, that this is the issue a series collector cannot complete without, and it is why a 1909-S VDB sits where it does. Having it as a value rather than a note means you can find every key date on the shelf at once.
What is the Certification number for?
A slab. If the coin has been graded by PCGS or NGC, the certification number on the holder goes here — 2851764-001 — and it is the field that ties your record to a public lookup anyone can verify.
๐ Unlike a watch serial, a cert number is designed to be looked up, so it is not a privacy risk in the way a serial is. It describes the holder, not your house.
How do I record the actual grade?
In the description, in the market's own words.
Coins are graded on the Sheldon scale — MS-65, AU-58, VF-20, PR-70. TrophyShelf’s condition control offers the universal six instead: Mint, Near mint, Very good, Good, Fair, Poor. The graded-slab segment belongs to trading cards, so for coins the grade lives in the description.
So write the real grade at the front of the description, in the form the market uses: MS-65 (PCGS), or VF-20, cleaned. Fill the certification number beside it. Between the two, the record is accurate and easy to read.
What does the AI fill in for a coin?
It reads what is struck on the coin — denomination, year, country — from a photograph. It also fills in Condition when the coin itself is in your photos, with an AI badge. Paid, Est. value and Where acquired are yours to fill in.
The grade stays yours too, and that suits coins: a grade is decided under a loupe at an angle, so you write the one from your slab.
