Full Metal D60
Do you have a roll table with 60 different items? Want to scare your level 20 players by rolling a full metal d60 for damage when that Tarrasque attacks? Then this is your die! Just imagine their faces when they here this thing hit the table after beating the armor class of that smug level 20 barbarian. That is a sight to behold.
And if all else fails, you can use it as an improvised weapon* that hits harder then any d4 could do.
