[@Tortoise] Sorry it took me so long to go over your sheet. 

She seems perfect for this sort of roleplay. Though please add a bit more to her personality, if you would. 

[@Duck] That's difficult for me to answer. You do, of course, know that 20 copper commons is 1 silver and 20 silver is 1 gold. How about this... Generally you can consider a copper common 1-2 USD, and a Silver Lordling like 50$ bill, and Gold is either 100-200 USD depending on where you are. I know that is somewhat still vague, but I hope it helps quantify things. 

Like you can usually buy meals by using commons, and very expensive ones with silver. A room at an inn will certainly cost silver or gold, depending on how swanky it is. 

Does that help?
