Most partys send someone off to the pawn shop with unwanted loot and throw the coins into the 'trues' pot before the split. Other than that, it's pretty much up to the party....I've had groups tell Muir to donate it to her temple but then there was 3 Mistys and her favourite gnome in that group
I'm all for good RP and everything but if it's 2am and I've just done a 6 hour run, I want to be rolling once and only rolling again if someone rolls exactly the same as me and we're the two highest.
1d100 while maybe not making the best RP sense, does make it quick and relatively painless so I'm not in favour of changing it.
