This question about alternate terms for coins focused on the use of ワンコイン, but it got me thinking about slang terms for money in general.
In all the years I've been in Japan, I don't think I've regularly heard people use slang terms for money they way they do in, say, North America.
In Canada, everyone routinely uses "loonies" to refer to the one dollar coin.
A guy from the US recently said to me, "it's all about the Benjamins." Bucks, greenbacks, cheddar, and more are a matter of regular conversation.
I could probably say, "it's all about the Fukuzawas," but I think they would see it more as me at play than using a commonly accepted slang.
On the coin level, in North American English, we almost exclusively use quarters, dimes, nickels, and pennies in place of "25 cent coins", "10 cent coins", and so on.
By contrast, I can't think of anyone referring to a hundred yen coin in any way except its value,
Am I right in thinking that Japanese on the whole don't really feel a compulsion to give nicknames to their units of currency? A little web searching hasn't turned up a wealth of terms that I was unaware of, but my Google-fu is always a little lacking in Japanese.
By the way, bonus karma points for anyone who can translate "it's all about the Fukuzawas." I can't figure out how to convey the vague "it" part which refers in a vague way to life or living or "the reason to do stuff".
