DittoI tried, but when my groups started travelling from region to region I was hard pressed to remember the names, so we just quit worrying about it.
Even though I do have ancient collectible coins as part of my treasure awards tables. So if the party takes the time to find collectors they can get up to 10 times the face value of the coin. They rarely do though. They even passed on 112 ancient platinum coins that were worth over 11,000 gold to the right collector/s. Gave them away (spent) at face value. Oh well, their loss.
Ditto this. We keep track of gold only; all other coins are too much hassle. We also don't really keep track of the weight of coins, but honestly by the time that matters we usually have a bag of holding anyway. Sometimes we find gems or something, but those are pretty much just treated like gold.Not very detailed, each pc has written on his sheet how much gold he has, and when they find precious items i tell them the monetary value. SO, for example a character could have
"340 gold, a bag of gems worth 200 gold and a silver chalice worth 50 gold"
