Happy October! The contest is over, and there were two entries only:
@funnel and @nellita66
The post and the entries can be found here!
Since there were only two entries, I decided to do a coin flipper on random.org, where @funnel has heads and @nellita66 has tails, and here's the video of the pick
According to Wikipedia, the obverse of the coin (a.k.a. heads) is the side that is localised/nationalised for each country, while reverse (a.k.a. tails) is the other side that shows the whole EU, as well as the standardized value of the coin.
As such, @funnel won 10 SBI Shares, while @nellita66 won 5 SBI shares. The shares have been sent, so congrats!
