I have a physical Litecoin based on a Casacius Bitcoin. I have the public key and see that the Litecoins are there.
Peeling back the seal/sticker revealed a Mini Private Key, but I'm having trouble importing it into Litecoin Core,
importprivkey(…) gives me the error message
Invalid private key encoding (code -5).
What do I need to do to import the Mini Private Key?
