How to redeem lost forks from Casascius Coin

[andyandyuk]

Hi,

I redeemed a 1 BTC Casascius coin a few years ago for BTC, BCH and BTG.  However, I understand there are other forks that I missed out on such as BSV etc.  When I try to use the private key there are no funds available for these other forks. 

Is that because once redeemed the private key becomes public and anyone can then use it?

Is there anyway to recover lost forked coins from redeemed Casascius coins?

Much appreciated.

The amount that you have depends on the amount of coins that you have at the point of fork. When did you move your Bitcoin Cash?

BSV was forked on 15/11/18 at the block height of 556766 from Bitcoin Cash. Did you move your Bitcoin Cash before that?

Your private key will always remain private unless you leak it by mistake. It doesn't matter if you used it create a signature (create a transaction and spend your coins).
If your address doesn't show any forkcoin balance it is most probably because you spent your bitcoin before any of those forks took place. For example BCH fork was on height 478558 (2017-08-01) and you would only get BCH if you had spent your bitcoin in block 478559+. Subsequently if you didn't have BCH you can't have BSV either.

Hi, I redeemed a coin in 2018 and one more recently (a few weeks ago).

I managed to recover the BCH and have them in a wallet.  I no longer have the BTC so that is the problem?

What method/ wallet did you use to redeem / sweep the cas coin?

Search your BCH address on Blockchair.com: if you moved the BCH before it Forked into BSV, your BSV will be on the same address as your BCH now. In that case you'll find BCH-A too.
Note that BCH, BSV and BCH-A don't have replay protection. If you move BCH, the others will likely move too. So don't move them to an exchange before you're certain they're properly split.

Some wallets might also not understand Casascius' mini-private-key, in that case you'll have to convert it to a normal private key first.

You'll probably have $11 worth of BCD too. Most other forks I wouldn't bother about.

Hi, I swept the private key into electrum for the BTC and created wallets on coinomi to sweep the forks.  BCH and BCG worked but not BSV.

on coinomi

See BCH(ABC)/BSV Fork - Information/Splitting.

It'll be because of the lack of replay protection... when you moved the BCH, it likely moved the BSV as well... if you look at the BCH address on a BSV blockexplorer you should be able to see an identical transaction to the BCH one.

So you swept the BCH into a Coinomi wallet? If so, you should be able to access the private key to get the BSV... but you'll need to make sure that you properly split the coins. You need to get some "split" BCH dust to add to a BCH transaction that sends all your BCH back to yourself... having the split BCH dust added in will make the transaction "invalid" on BSV chain... then you should be able to move the BSV.

Thanks all.
