Your collection
Import your Numista or CoinSnap collection
Export your collection from Numista or CoinSnap as a CSV file, upload it with the Import button, and check every match before the coins join your collection.

Export from Numista
On Numista’s export page for your collection, choose CSV, not Excel. The importer only accepts a .csv file, up to 5 MB.
Then tick the columns below. The upload window checks for them and names any that are missing, so you can export again with them ticked.
- Type: Country, Issuer, Face value, N# number, Title, Composition.
- Version: Year, Gregorian year, Mintmark, Comment.
- Collection: Quantity, Grade.
The N# number is Numista’s own number for a coin. It is how your coins are matched to the Florin House catalogue, and how a coin that is not in the catalogue yet is brought straight in from Numista rather than searched for by name.
Export from CoinSnap
Export your collection from CoinSnap as a CSV file. It needs four columns: Country, Denomination, Year and Grade. A Subject column, if your export has one, is used alongside the denomination to name the coin, which helps match commemoratives.
The importer reads no quantity from a CoinSnap file, so each row counts as one coin.
Upload and review
Choose Import, pick Numista or CoinSnap, and drop the file in. Every row is checked against the Florin House catalogue: by N# number where the file has one, and otherwise by name, country, year and denomination.
Before anything is added you see three counts: coins already in your collection, coins found in the catalogue and ready to add, and coins not found that need importing first. Review coins lists every match so you can check each one and untick any that are wrong; Import & Add All (or Add All to Collection, when every coin is already on Florin House) does the lot in one go.
Coins that were not found are looked up on Numista and added to the catalogue. Those lookups use a monthly allowance of Numista requests that the whole site shares. If the allowance runs out part-way through, the lookups stop and the coins already matched are still added; the ones it could not look up are counted as skipped, and can be imported from the start of next month. Importing a single coin from the review list tells you when the allowance has run out.
Keep the page open while coins are being imported. Leaving or refreshing it interrupts the import.
What carries over
Three things come across with each coin:
- Quantity — how many you hold. From a Numista file; each CoinSnap row is one coin.
- Grade — saved as the coin’s condition in your collection.
- A note saying “Imported from Numista” or “Imported from CoinSnap”.
Mintmarks and your own comments are not copied. The importer reads them to tell apart two rows for the same coin, and shows them while you review, but neither is saved to your collection. A coin you already hold in the same or a greater quantity is skipped, so importing the same file twice does not double it.
Where to find Import
When you are signed in, Import is in the header, beside the notifications bell, on phones as well as on a computer.
New accounts are offered it while setting up, too: the Build Your Collection step has an Import collection from Numista or CoinSnap button.
Once the coins are in they behave like any others in your collection: they count towards its total, and you can sell one from there.
