ybotherTo answer both questions at once, yes you are getting 120 coins. It will work out to 40 each of the 3 denominations in the Magic Mixed Set.
I like your idea of doing a 'surprise' set, but don't want anyone to get the set they can't/won't put to good use. We picked this set for the first drop because it won our poll for fantasy currency. Obviously this one is going well so feel free to make a poll for the sets or bundles you would like to see.

Basically I kept the same format as this drop (4 mixed sets) and then grouped the sets into somewhat logical groups. I left the magic coins out because there's this drop already and everything else fit into nice groups of 4.
If people want more surprise options I can add those in. I'll be keeping an eye on the discussion there.
It would be très cool if there were ≥1 "surprise" box in this 4 box set.
