Well, two thoughts here:

There is an exchange money skill.

and secondly, have you ever considered the "low" coins are mostly flavor and
totally shitty, don't you think some "easy" cheap way to turn them to gold
sort of defies the point? Oh, and also, quit being a lazy *cheap* fucker,
walk to bat city. Either be lazy or cheap, or hell even lazy AND cheap and
silent. But seriously, I find this really amusing, people lobbying for some
change so they can convert low coins to gold, give me a break. In the time
you spent typing these messages you could have made more gold than the changes
you suggest would hav netted you.
