Presumably the Goblins who make Galleons do something to them 
with Goblin magic that can't be imitated by wizard magic, so that
counterfeits can be detected, but that was not mentioned when 
Hermione handed out counterfeit Galleons as DA meeting notices.

What stops the Weasleys from transfiguring autumn leaves into nice
unshabby robes and pajamas? Or charming the robes and pajamas they
have into better ones?

Clever and magically powerful as all those Weasleys are, why don't 
the kids hot-rod up their brooms?

If a powerful wizard/witch transfigures an animal into a human, does
it gain human intelligence? As use of language is part of what it
means to be human, is fluent knowledge of a language already installed
in the new  human brain? The human language it's heard all its life,
or the language the wizard/witch speaks?
