The 2024 ones don't which is what I imagine are being released - see below.
I haven't found this one in circulation by the way, so no claim to the prize/bragging rights, but many are for sale on ebay etc.
copying off the internet is bad form you can tell from a left click can't you
the year set coins have a mint mark as well
Hey it's only a bit of fun there is no prize at the end of it - I would expect them to be found in one of our big cities like Birmingham or -Manchester - Glasgow or Coventry, they usually get released in these places
