Staying in Winnipeg for a while?
This is a pretty decent attraction, but only if you have some time to kill. If you like to watch the people at work and the machines used to mint coins, you'll have a great time, even though there's not a lot of action going on.
I myself was more impressed by the giftshop. I stopped collecting coins 11 years ago, and I only wish I'd known a shop like that one then.
Anyway, this is the mint where the circulation coins for all of Canada, and many other countries, are struck. If you wish to see how collector quality coins are minted, you should visit the mint in Ottawa.
The mint is located on the outskirts of town, on Lagimodiere Blvd., so you will need a car to get therem, and I can't really think of any other good attractions in the immediate surroundings.
