I ended up just importing them and sending them to a newly generated Ledger wallet, I skipped the offline signing. I had to keep it simple as a newbie.
Painless success!

Thank you so much to you all for your answers and your time, you really made it all feel safer to do this!
I hope your posts will help others in the future, I sure will come back and read over it next time if I’m unable to sell my other coins to collectors over the next couple of years.

The video was very good, thanks. But how do I proceed in the start with the private key, do I use sweep on the offline wallet?
.

Then you can follow the same cold-storage setup procedure to create, sign and broadcast a transaction that'll send the entire funds to your Ledger.
I noticed that the video is old, in the new version, you can export/import PSBT transactions as file via "Share->Save to file".
Note: Confirm every character of the address before broadcasting the finalized transaction.

Will this change the steps so the video wont explain everything I need to know?

Do I first import instead of making standard wallet then send it to the address.
This works.

Or do I make an standard wallet then import them send to the Ledger address?
This also works (but takes 2 transactions, 2 transaction fees, and means your cold storage funds spend a bit more time in a hot wallet.

Are sweeping involved in any way in the procedure?
Any Electrum wallet can sweep a private key directly to the Ledger address you enter.

Basically, you have options Smiley What I would do, but that is my personal preference, is import the private key into Electrum, then make the transaction to the Ledger (and this is the easiest method to add offline signing to the mix).

Thank you! xD

Is sweeping in essence just en extra unnecessary step vs importing if I just want it directly on my ledger wallet?
Import: add the private key to your wallet. Funds don't move.
Sweep: move all funds from the private key to a new address. Funds move.
You can't import a private key on a hardware wallet.

Feels like I’m getting stupider and more confused every time I read the posts.

So all I need to do is change from the default Electrum address to the Ledger address?
Yes. And check the address.

I always do Smiley

You can sweep directly to an address in your ledger wallet. You don't need to create a new wallet to do this.

My Ledgers are old now an will probably need to be updated. I probably need create a new Ledger wallet on an online machine, but there shouldn’t be much risk right? The Ledger is only receiving unless I missed something.

The Linux Live DVD is too complicated, but thank you anyway!

I will give the offline signing a try with 0.5 Casascius and report back. Thank you all so far!

Edit: Can I create a new Ledger Wallet on an offline machine?

Ok, so on the offline account I just use import in the start instead of sweep on an standard account?
"Offline Electrum wallet", yes, what you need is to create a new 'imported' wallet containing the private key.
This wallet is only required to sign the transaction that you'll create in the online Electrum wallet.

Where in the steps do I input my newly generated Ledger address?
During the step when sending a new transaction in the 'Send' tab of online Electrum wallet.
That'll be your recipient "Pay to" address.

Excellent, thank you!

About selling these. I live in Norway. Sadly there is no market for this here. I used to be very active here in the marketplace, and after being offline for some months my account got hacked and scammed someone. I registered again, and just posted a few posts, when I returned here some months later my new account had been banned for spamming(?). Seems to me this site isn’t very secure. I have a hard time trusting selling and buying here.

Thanks for the answers! Is there a video or step by step guide on this signing process? This seems very complicated to me.

You need two devices to be able to make an airgap/offline transaction. Please read the guide from Electrum docs here below

- https://electrum.readthedocs.io/en/latest/coldstorage.html

Or follow the guide from this video below.

For more security, it's recommended to sign your transaction offline.
To do so, you need to create a watch-only wallet with your address on an online device and another wallet with your private key on an offline device (preferably an air-gapped device).

Does existing Ledger qualify as offline device? Or should I generate a new seed like bitmover advices? Can this be done offline?

Hi, can I sweep the private key directly to my Ledger address, or do I need to sweep it to Electrum standard wallet then send it to the Ledger address ?

Also a noob question. Do I need to download and update Bitcoin Core to use Electrum?

Jeg har Casascius, Titan Bitcoin og noen andre fysiske. Er det noen her som er interessert i å kjøpe?
Vurderer å redeeme dem om det ikke er marked for dette i Norge :/
