Luckily yesterday was a down day and I wasn't in a selling mood - my broker shifted my MUG holdings into MUG (USA) instead of MGR.
I did notice, however, that in the US it appears that you can trade at fractions of a cent other than 0.05. Mug (US) was trading at $0.147 according to my broker. Talk about fine lines of profitin the USofA!
