Honestly I doubt they will retire stamps anymore. Look what happened to the few retired ones? They are SO rare that TNT has to do those Sloth auctions to reintroduce them into the economy. They wont retire rare stamps again.
the stamps from dr_sloth aren't retired stamps
they are stamps that were released in a very small quantity from mystery pic or Lenny Conundrum games
the rarest retired stamp is candychan stamp, and it was low rarity before it retired so there were a lot of them around
(or golden mr irgo, i dont remember the origin of that stamp though)
but anyways if the stamp is 3m now its probably an r95-99 stamp, which won't be retired...the only stamps theyll retire are the very low rarity stamps like the mystery island aisha stamps, those were only a few k before being retired and they shot up to around 150k
