Setting aside any complicated arithmetic, the knuckles on their own effectively give Grog:

a) +4 to hit from the strength boost (statistically about the same as having advantage)

b) +4 to damage

c) +1d4 damage when enlarged

d) He already has advantage on strength checks while raging, which is basically always, so this is redundant

e) Siege damage, which as Vegan mentioned, is mostly not going to provide a tactical advantage in combat except under very specific circumstances. Really, it just opens up fun story alternatives with Grog punching walls and doors and rolling comically large numbers.

Overall, it may indeed be the best item Grog ever picks up in the campaign (which makes sense story-wise) but it isn't so powerful as to be game-breaking.
