Very nice designs, the first one does have a masonic look to it, dont like the writing in the middle, make it look a bit busy but it is smart.
I do love the image of the continents, the second one would be loved by flat earthers, all together on one flat disc. we are also supposed to believe Africa is 14 times bigger than greenland! its all a conspiracy lol, moon? what moon, ive never seen a moon.
The 3rd one ticks all the boxes and a clever design, keeps all the sizes of fish theme from the fist coin, the steem logo cleverly kept central and the ship would look cool.
Im loving the 4th design and on first glance my favorite and would probably look stunning on a silver coin with the texture, if you held it close to the eyes and slowly moved it away id bet you could see the sailing ship from the 3rd coin hidden in the pattern! The second steem coin is going to be a must have whichever design.
