US money is fairly goofy. I have come to appreciate the yen and its lack of points, just straight up here is "one money" to here is "a thousand money". The values get pretty big pretty fast, but it feels good to make several million yen a year. It wasn't always this way. There was the 銭 ('sen') which is the equivalent of the US cent. You'll still see it when talking about exchange rates and I am sure in the depths of the banking world. Or if you get your currency converted on Steam.
I have no idea when or how I will use the 39 sen in my account. I do know that Steam's customer service took longer than I hoped and I will not be buying The Binding of Issac on sale. I can finally make purchases with my hard earned trading card sales, however.
