The cost and manufacturing process are prohibiting the number of coins we can manufacture. The current proposal suggests giving one coin to The Gridcoin Foundation to do with as it wishes -- auction for funds, hold, auction and burn proceeds, etc -- and the other to the miner of the millionth block. There are proposed contingencies regarding the 2nd coin as we might not be able to contact the miner. Full details can be found in the #branding channel on slack and we'll post a proposal on other community hubs once we gather feedback from this post and the conversation in Slack.
