I'm not sure it will be. I'm think people here use "money" more often than "coins" when referring to non-token coins already, or just use a number with a currency symbol in front (e.g. $3) if they're talking about a specific amount.
...
I just did some searching on the forum for "money", "coins", and "$" followed by each digit and it looks like "coin" is significantly more common than "money" even if you eliminate posts referring to Guilds' coin tokens. The variations on $X are all pretty sparse too, except "$2", which is about as common as "coin". € and £ also show up as currency denominators, but very infrequently.
Actually I'm not sure this is a reliable way of gauging anything. The search returns exactly 30 results for most of the "$X" searches, which makes me think there are times when it just stops at 30. Also I didn't take the trouble to eliminate non-Dominion subforums from the results so references to real-world money could be inflating any or all of these results.
So yeah I guess SirPeebles has a good point. People should try to make clear in some way when they are referring to coins vs. coin tokens.
