The first contract on Ethereum mainnet to carry balanceOf, transfer and a Transfer event together, deployed 23 October 2015. Supply 1,000,000, and it was never used.

The same token code as 0x3C655ccb35666579511489af88153517fc58b017, the first contract on mainnet with balanceOf, transfer and Transfer, redeployed the same afternoon with a supply of 1,000.

The October 2015 prototype where balances moved into a public mapping named balanceOf, with a lower case balanceof function returning the same value. Supply 200,000, never used.

Identical token code to 0xCAe62D22E8480b230d7aD93039167a0FfA7A2B8B, redeployed four minutes later with the same 200,000 supply. No transfer was ever made.

Deployed by 0x9b22a80D5c7B3374a05b446081f97d0A34079e7F, the account that deployed MistCoin eight days later. No constructor argument was given, so supply fell to the built in default of 10,000.

Byte identical to 0xE274d18EF7b194A1EDEbB04cfE297CFe1489ef65 and deployed two minutes and twelve seconds later from a different account. Supply 10,000, and the one call that reached it emitted no Transfer event.

The October 2015 prototype that was actually used, with eight Transfer events. Balances sit in a public mapping named balances and are read through a balanceOf function. Supply 132,325,360.
