Nickel Coins Being Pulled

I wonder if other mints will like this idea and start to do the same.
Nickel is not an expensive metal. I wonder how much money they actually save in production per coin?
Of course there are millions of these coins, but when I think of the costs involved in gathering, transporting, melting and then producing new coins....will all the effort be worth it?

An interesting situation may develop regarding the last of the old Canadian nickel composition coinage.

As the RCM diligently removes the old nickel composition coinage, eventually there may be more of these coins circulating in the U.S then in Canada itself.

In the U.S., many 'stray' Canadian coins have, do, and will continue to circulate.

There is currently no removal policy for Canadian coins in the U.S.

Therefore, in the future, the U.S. may be the best,perhaps the only place to search for older Canadian nickel composition coins.
