the coins are part of a way for them to not seem as scummy: "look, we aren't a cash-grab gaccha! you CAN get the special units (after spending a year's salary)"

So they have them set in 3 versions: red coins are dokkanfest coins. You get them for summoning on dokkanfest banners and the coins can be used to trade for dokkanfest exclusives (provided they are in rotation).

yellow coins are for Lrs that appear on the Lr banner (mostly just oldest lrs, but they are consistent at adding new lrs to the list each time a new Lr is released)

blue coins are for non dokkanfest, non lr banneres.
