I have seen the tracking code of this TB/coin during my trip in Munich for the Giga event.
It may have been something really cool or just some code written on a wet piece of paper, I couldn't tell out of the huge list I've written down on that day.
So I just do this batch log which I hope is fine given the overdose of TB I got at the Giga event.
Anyway, thanks for sharing and sorry if your TB was exceptional and diserved a better log, it is just to much of them at once.
