So just to compare the Miner's Gold Dynamite and Mace effect:

3 Mace (+9): 6% Coin bonus x3, 240% chance of 10 coins so that would be about 24 coins per destroyed obstacle.

Gold Dynamite (+9): 3% Coin bonus x3 (5% for blessed but still less than Mace), 6 coins per destroyed obstacle x3=18 coins per destroyed obstacle.

So the Mace is better if you can collect all the coins it generates. Gold Dynamite might be better if you're half asleep though.
