I think the Golden Shovel needs to be buffed.
Currently, the only difference between a normal shovel and a golden shovel is that the golden shovel doesn't break.
Worker potions already make shovels indestructible, so there is essentially no difference between a golden shovel and a normal shovel, since no one digs without a WP, especially considering the golden shovel doesn't increase the chance of finding shells.
Meaning you have to dig 50,000 shells for a normal shovel with a slightly different look.
And that's in addition to however many shells you dug before achievements were added. (I already had 51k shells dug before they came out, and had to get up to 101k to get the golden shovel.)
Not only that, the achievement reward from mining (Golden Hardhat) increases the speed at which you mine, so it's only fair (and consistent) that the golden shovel would do the same for digging.
I think, worst case scenario, the golden shovel should give you the same or greater chance of finding shells that a worker potion would give you (and be stackable with worker potions, since the golden hardhat is).
Best case, the golden shovel would have a chance to give double shells, have reduced freeze, or it should be automatic (hold D to keep digging over and over)
