The the action 'Look' on money has changed in recent
version, to return: 'You see a coin'
instead of 'You see a money'
But, a player uses 'Look' to find information on how
to, for example, /drop an item - and money is called
money not coin or coins.
So, I suggest that 'Look' should return 'You see money'
- which is still accurate usage even in the singular
(of looking at only one coin).
