We do not yet know whether the shop lets you buy a later item directly or makes you work up through every tier, so both readings are shown.
Enter a whole number of Gold to see how far off you are.
This will not tell you whether to upgrade your shovel or your detector first, or when an upgrade pays for itself. Both need Gold-per-hour and the dig/clean/sell time split — we found no source publishing either. A point of luck and a point of dig power are different units.
