I would like to transfer my colection from UCoin here

i have over 400 coins registered on ucoin. Is there any way i can import them all withoust spending days to add them manualy?

No, you would need to know all the keys for every exact coin type/variant of Numista and ucoin may have other variants etc.

Also 400 coins is really not that much to be honest especially if you already logged them into ucoins (you have the reference number, quantities and grades), we had people with far over 10.000 coins doing it. 

Open two browser windows (Numista on the one, ucoins on the other), arrange them side by side, play some music or watch a movie and it's done in a few evening or a weekend. That's how I would do it.

If you name implies you know how to program you could probably find a way to automate the migration somehow. But if it goes like my automatization projects it will take longer for this solution to work then it would have taken to simply doing it yourself 😅

As there is no such option now and this is the ticket for something else, I will procedurally mark it as “rejected”.

I made a website to migrate from ucoin to numista.

Read the instructions before using it

Hi! Unfortunately, there's no automated way to import collections from uCoin to Numista - you'll need to add them manually. I know it's frustrating, especially with 400+ coins!
 

However, I created a comparison tool that can help you significantly during this process:
 

What it does:
 

• After you manually add your coins to Numista, it compares both collections and tells you exactly which coins are missing or have quantity differences
• This way you don't have to wonder "did I already add this coin?" or discover at the end that you missed some coins (like I did - I missed 3 out of 1000+ and had no idea which ones!)
   

How it works:
 

1. Export your collections from both uCoin and Numista (simple Excel exports)
2. Run the Python script
3. Get detailed reports showing:
   • Coins only in uCoin (still need to add)
   • Coins only in Numista (added extras by mistake?)
   • Quantity differences between both collections
      

The tool is free and open source:

https://github.com/Domandrenog/Coin-Collection-Comparison-Tool---uCoin-vs-Numista
 

It won't do the manual work for you, but it will save you from errors and help you track your progress as you migrate your collection. You can add coins in batches and run the comparison to see what's left.
 

Hope this helps with your migration! 🪙

I said that I MADE A MIGRATION TOOL, so yes, there is a way to do it.



The only limitation is the amount of API calls allowed by numista, so some people may take a few months to complete migration.

Just saw this reply now, sorry!

Yes, I actually created a migration tool to solve this problem, so there is a way to do it automatically.

The main bottleneck is Numista's API limit of 2,000 requests per month. For users with large collections, this means the migration could take several months to complete. However, the tool tracks progress automatically, so you can pause and resume each month without losing any data.

Not the fastest solution, but it's the best workaround available given the current API restrictions. Hopefully Numista will consider increasing the quota in the future!

I would pay for more calls to the API to be able to migrate all of it with one shot..

I wrote twice that I MADE AN AUTOMATED MIGRATION TOOL, then you say that you saw, then you say you developed a tool like this… There's no problem if you developed it or not, it's not a such a big deal, but why do you simply ignore what another person did? why did you say it's impossible and suddenly when I write that I did, then you say you did so? it's kind of weird. We can help each other without self-conceit.

Just now:

Hi! I just tried to send a file and it worked fine.. I can make a videoconference with you and try to help (you need to pause the video at the point to put API key, so that I cant see it).

Rodrigo,

Thank you. I think the problem is with the program's connection to Numista, or maybe with the regional settings. I'll try using a VPN, or a different browser, or something else. (connected from Poland, Chrome and Brave browser)

Regards
