The "P" is for Perth Mint. All coins would have the mark of the mint where it is produced, although the Panda does not have mint marks and there are extensively produced throughout China, I think the have Chinese govt mint all over. All U.S. coins have mint marks, and those without are U..S coins produced from the Philadelphia Mint.
Beautiful Koalas, @djohan! Thanks for the show.
Be safe and take care, my friend 🥰🌺🤙
thank you silversaver888, I didn't know that although i had a guess P would meat Perth. I am also collecting the panda coins when i visit China as much more expensive outside.
