idk, but I noticed something similar about hamburgers of a big chain seeming to shrink over the years and thought its shrinkflation. It took me years to realize: It was just me growing.

As a non canadian scrolling all. This title was so confusing. Nice chuckle for the morning once I read and realize you where talking about a coin.

I doubt it, because many coin-operated mechanisms are designed to measure the weight of coins before accepting them.

I honestly don't think I've seen a King Charles loonie. If I have, I didn't notice the difference in size. Still seems strange to me that coins or currency doesn't have the Queen still.
