I beleive it was June 1999 when I found GPH $5 replacements. I was hoping to get FNX B-T. GOT and GOV were already known by some collectors. I think the change came in the 5s sometime during 1998. I don't have any info on the other denominations but I will see what I can find.
These notes were different than what collectors were used to so someone came up with the name " inserts " and that has stuck for quite a while. The confirmation of FEP, by the BOC's Education Team, referred to them strictly as replacements. Maybe its time we followed the BoC and simply used the word, " replacement ".
