Wonder if 'Remainer' coin collectors will add the Brexit coin to their collections?
Speaking as a remainer, I will add it to my collection if I come across it in circulation or swap it with someone who has a duplicate/doesn't want it. I won't specifically go looking for it on the RM's website, but I don't do this with other new issues either. I don't see the point of boycotting coins representing political views I disagree with; I have plenty of coins from Nazi Germany, the USSR and Fascist Italy in my collection, for example, but I have nothing but contempt for those regimes.
But I suspect any that make it into circulation will be removed by leavers wanting to add them to their Boris shrines.
I think the Brexit coin was a bad idea, not because I voted the other way and not because of the chaos caused by the moving of the date (that's not the Mint's or the coin's fault). For the same reason that we tend to avoid commemorating living people on coins, I don't think we should be commemorating current political events either. And yes, I'd put the 1973 issue into that category as well; I have always thought that was a bit of an oddity given that there were no commemoratives for other events at the time they occurred in that period. (The 1992/3 and 1998 ones are a bit different, as they commemorate an anniversary and the rotating EC presidency.)
Commemorating current political events is divisive, Brexit being the archetypal example. There wasn't a Good Friday Agreement coin either, and that was on the face of it a more generally positive event but nevertheless with its detractors. But even when an event isn't as charged as Brexit is, it takes time before its true effect on history, for good or bad, is measurable. This coin just smacks of triumphalism, tbh, and regardless of your view on Brexit, rubbing the other lot's faces in it just isn't helpful.
