Your problem is not difficult but how you say it make it look difficut.
Do you have 10,000 of doge, infinitecoin, bitcoin different or all of them is worth the 10,000coins. Or do you mean you have $10,000 worth of coins in your cold storage.
Again. You say you have
QR Code available. Did you used paper wallet? or Hardware wallet. Because paper wallet normally has
QR Code.
Hardware wallet need computer to store the private key offline. Did you print it then or you have a screenshot that gave you the
QR Code.
As said by someone above, use a safe scanner and scan the code to see the result you will get.
