Is that still going on where you live?
I haven't seen OR heard anything about "the coin shortage" since June 2020. Not 2021 -- That's 2020.
Haven't seen a single sign, not heard a single person mention it, etc. And BOTH of those things were true a year ago. I saw signs everywhere and everyone was talking about it.
Are you sure about your news source? Maybe they are just a clickbait site, and changed the date on the article to "refresh" it and get more clicks out of it?
