Sorry for so late to answer . Yes it from circulation. But it has been in a coin flip from the mid 1970's. It was part of my very early collection. Canada and Mexico were the only non-US coins I could really find. And Canada was the first country I put in coin flips and put in 20 pocket coin page. Just starting out I did not know anything. Iam just putting Canada back together. What a mess, The coin flip it was in was no longer white , more yellow. I kept a 1929 nickel in an old flip just for remembering. This one even has rust on the stables.
Us old farts.
