What obsolete coin denomination would you like to see come back, would it be the half cent, two cent, 3 cent, 20 cent, gold coins $2.50, $5, $10, $20 or if your Canadian the penny?
I am not sure people would like the $2.5, so I would prefer the $2 equivalent and a $5 coin. get rid of this paper that wears out so quickly, and let the mint generate profit for the country.
