i wish so badly that there was a singleplayer shop and a money converter, so you can put like, 10 pennys and get a dime (10 coin) and so forth. and be able to find money in dungeons. I can't find a mod like that. maybe the charge cards could have damage values, so you can see how much they have left. All could be configurable so you can disable them so you can use it like you've intended. i like this form of currency best tho.
