For coin collectors
A catalog for your coin collection
Describe every coin the way numismatists do: country, denomination, year and mint mark, metal, weight, grade and catalog number. Keep the obverse and the reverse side by side, see what you are missing, and share the collection when you are proud of it.
The Coins template has the fields numismatists use, a list of grades from Poor to Proof, and a field for the reverse side. You can change everything afterwards.
What to keep
What to record about a coin
These are the fields of the Coins template. Together they describe a coin so that it cannot be mixed up with another.
-
Country and denomination
The base of every record: where the coin is from and what it is worth on its face.
-
Year and mint mark
The same coin of the same year can differ by the mint, and the difference can be a big one in value.
-
Mintage
How many were struck. Low mintages explain a high price.
-
Coin type and metal
Circulation, commemorative, proof, bullion; and gold, silver, copper or another metal.
-
Weight and diameter
Measured values help to spot a variant or a counterfeit.
-
Catalog number
The number in the catalog you use (Krause, Numista or a national one), so that you and others find the same coin.
-
Grade
Poor, Good, Very Good, Fine, Very Fine, Extremely Fine, About Uncirculated, Uncirculated or Proof: one scale for the whole collection.
-
The reverse side, purchase and estimated value
A photo of the other side, what you paid, where you got it and what it is worth now.
How it works
Your first coin in three steps
-
Create a collection from the template
Pick “Coins” when you create a collection. The fields, the lists of countries and metals and the grades are ready.
-
Add coins with both sides
Put the obverse as the picture of the item and the reverse into its own field. Add weight, diameter and the catalog number.
-
Search, filter, share
Filter by country, metal or grade, group by country, and publish the collection in the Gallery.
A short guide
How to describe a coin collection well
Collectors compare coins by the same few facts. Write them the same way every time.
-
Describe a coin by country, denomination, year and mint mark
These four things identify a coin. Leave none of them out, even when the mint mark is just a missing letter.
-
Grade honestly and with one scale
Grading is partly a matter of opinion, so decide how you grade and keep to it. If a coin is in a sealed holder from a grading company, write the company and the number in the notes.
-
Record the catalog number
It saves a long description. Use the catalog your hobby uses and write the number in the same form every time.
-
Weigh and measure
A scale and a caliper take a minute and catch variants and fakes that the eye misses.
-
Do not clean the coin and say so
Cleaning usually lowers the value to collectors. Record the condition as it is, and note if a coin was cleaned in the past.
-
Photograph both sides on a plain background
Use even light and the same distance. The photos are the record of the condition on the day you bought it.
FAQ

Poor, Good, Very Good, Fine, Very Fine, Extremely Fine, About Uncirculated, Uncirculated and Proof. You can add or rename the values if you use another scale.

How do I mark duplicates or coins that I want to swap?
Add a field “Duplicate” of the type yes or no, or a list “Status”, and filter the catalog by it.
