If there is an egregious error like this where a coin in a
PCGS holder is an outright, easily provable fake, it seems that
PCGS will work with you and take care of you... The idea is they will generally at least give you what you paid - save those receipts!!
As mentioned by Mathieu, this is a sequel to the story about the 1686 "Royal" 8R... It is what it is - shows that
PCGS still needs to step up their game when it comes to World coins (especially when such an error occurs on a series like Spanish Colonial, which is obviously popular with and well-known to the U.S. market).
That's an interesting Lima 1R... older fake or quaint modern fabrication? That seller... grr, he out-cherrypicked me for something very good last year. He's on my list. GRRRR.
