The penny drops

After years of debate, Canada is losing an old friend--the penny.

Excuse me, this is an emotional moment for me.

It looks like they will continue to be legal tender even after they are no longer produced, so it will likely remain illegal to melt the old copper ones down (for Canadians, those would be 1996 and earlier). But it seems we won't be able to go to the bank and get them any more after the fall. I'll need a new hobby.
