Why do you think so? How do you know this, if you received it from an individual with a story? Again, how do you know this, and how do you know it was 'crappy" and should never have been, and that it lowered the value? Is it not just as feasible, that the piece was switched out, if you have absolutely determined the piece in the flip is of inferior quality? Your photos are suspect, as to whether the piece is as shown.
International Coin Certification Service, which is Canada's pre-eminent and well regarded coin grading company, encases coins in a PET film envelope that is sealed in a plastic flip. The ICCS grading certificate is sealed in the other side of the flip.
Not sure if the cert picture matches the coin. The photo cert is to dark for the pictures. All of my photo certs match the coin, I have one silver Eagle photo cert that I can't match, but that is because there are no contact marks on the pictured coin, but there are marks on the coin. That just means to me that the coin was mishandled after the picture was taken. I have been collecting ANACS Photo Certs since about 2006 and have over 100 of them and it includes all of the different type certs and one from the ANAAB.
