Hi Figleaf,
Thank you for your response. What I'm trying to do is to create a small group of 'friends' where I live, so we will be able to order coins to some mints directly, sharing costs. I hope that, doing this, I'll be able to get coins which I can use to interchange later with other users, especially in those countries where it isn't possible to obtain coins from the mint through Internet.
I'll take a look to the thread you've mentioned, in order to understand better what I can offer and ask from others.
