gold ratio

wondered if anyone could recommend the right sort of ratio for making gc, ie, gold mines (i have 5) gold smelters (i have 1 and coinage (i have 1)
would of course like to optimise them to the best capability but not sure what is best.

many thanks

1 level gold mine
1 level gold smelter
1 level coinage

Yep, 1 of each all at the same level. Only run them buffed, and higher level upgrades mean you'll get more for each buff.

I have 12 gold smelters (1x lvl1, 9x lvl2, 1x lvl3, 1x lvl4) and 13 coinages (5x lvl1, 5x lvl2, 2x lvl3, 1x lvll4) and 3 gold mines in sector 2 are lvl5 and using them like buildings - refill and buff with 3x buffs. In sector 9 I build gold mines on lvl2 and then buff with Irma's baskets and if only that 5 works I must have 2k gold ore in storehouse before run all gold smelters and coinages. All of them with buffs. I have production 1436 coins / 12h.

build some more storehouses and those 1436 coins will increase, just saying

Good point, also upgrade to level 5 and use the 3x buffs for even more profit and less coming back to rebuff.

Give your Geo's the gold science skills, bigger mines with faster production. Also the more explorers the better to bring back free coins on the medium search and free ore on the long and very long searches.
