all addresses to these public keys start with 1, which means that they are in the range of 160 bits. That's what I read on the forum. 
Okay, if you believe so...The early coinbase transactions were P2PK type with private key very likely in the full range of 256 bits and unique relationship of public key. Why do you come up with the stupid idea of public addresses when you speak of Satoshi's 50BTC blocks or others from the very early days that haven't moved until now?
Why do you think you would've have the "right" to steal the coins if it were possible (hint: it isn't). What a deranged moral compass...
But go ahead, waste your time and energy with possible 296 public keys to match just one P2PKH public address. You're certainly the hero of 160bit-land who thankfully doesn't understand the very basics.
