The first 50 BTC ever
The Block reward Satoshi received for the Genesis Block is stored under 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
These original 50 BTC are unspendable, since the Coinbase transaction, which clears the preservation of the block reward, was not added to Bitcoins‘ global transaction database.
Whether Satoshi intended it to be that way or if he simply forgot, is not known. Adds to the mystery of the Bitcoin founder.
Ah
What if it becomes spendable someday maybe after coinbase was added to the list
You cannot do that anymore. Those BTC are blocked
