Why not sell the coin? If you didnt scrape the code yet, its selling with a 50% premium as those are virgin bitcoin...

Those coins have mini private keys, right? I'm not sure if Electrum takes those.
You can import mini private key on Electrum. We discussed about it recently on this thread: S-starting mini private key sweep

In case if it does not work there's a way to convert the mini private key to the WIF key by pasting it to bitaddress.org(it should be run offline for safety.) and then import to Electrum offline.

We should educate people to download and verify such "offline page code" from the respective Github page. The page code of bitaddress.org is linked at the bottom of the page to https://github.com/pointbiz/bitaddress.org.

As of today and since Chrismas of 2016 the latest release is https://github.com/pointbiz/bitaddress.org/archive/refs/tags/v3.3.0.zip, inside the zip is a folder with the offline html file together with a GPG signature file. Do not omit to verify that the file's signature is OK.

OP should not use the offline version on his online daily computer and it wouldn't be any secure even if you turn off any network connection. Possibly existing malware could still steal a private key and just wait until the computer goes online again. It's bad opsec to mess around with "naked" private keys on an online device even if it is at that moment offline. You need a secure offline environment that you can safely dispose afterwards and that doesn't leave any traces on a digital device. Work in a live Linux that only runs in RAM and is verifiably offline.

Considering the value of those coins, you should probably keep the key away from an online computer. Learn how to sign offline. It's more work, but there's no need to risk anything.
Yes, Casascius has Mini private keys imprinted on the back and it should work on Electrum sweeping and import.

You should use the format  p2pkh when recovering in Electrum.
That is true, but it is not necessary. The private key would work as well as adding p2pkh: prefix to it or not. But if the address is starting from 3 or bc1, that is when their prefixes are needed. For legacy address, it is not necessary.

Remember that you probably have a lot of money in bitcoin forks as well.
After you have sold your bitcoins at coinbase, you can try to recover your Bitcoin Cash (BCH) and bitcoin SV (BSV). They are worth some money as well.

There are many wallets which support those coins. But remember, move your bitcoins first (as they are the most valuable coins you have)
You are right. I think this guide should still be of help: LoyceV's Bitcoin Fork claiming guide (and service). But I hard that Coinomi is having issue. I am not sure about this. I have stopped using the wallet since 3 years ago.
