I mean, usually my #dnd players strongly dislike tracking encumbrance, so the coins might as well be weightless.
Something I think people tend to forget about is the practice of "free lunch". Sit yourself down at the bar, order a drink, and you get access to a whole lunch menu as long as you keep drinking. It particularly makes sense if a pint of beer &/or a single lunch actually costs slightly less than a cp, so two beers would cover the cost.

Also, totally makes sense they would call them gold and silver if they inherited the roman Librae, Solidi, Denarii currency system
