All the paper looks very, very white to me. I would not be surprised if you put them under a UV light that they would be printed on modern high bright paper. But without stamps in hand it is hard to tell from images.
Thanks Don. That's a clear red flag the paper doesn't match clearly visible that something is wrong with them.
Firstly, placing them on a white background so that the margins disappear just screams deception.
Yes you are right interesting is that the paper of the scott 523, 524 and 547 looks the same as the 1850-1860 issues.
Secondly based upon the colors of the stamps which are circled in red I would agree on the perforated proofs assessment. OR they could be outright LaserJet printed creations.
Having looked again on the scans they look to white that the paper is 170 years old so they are indeed product from a laser printer. The perforation are the second redflag of this stamps.
Also that the paper is in all stamp on the same tone, withouth any discoloration mold stains couldn't be true that they are genuine.
Hey thanks very much I appreciate it to have your honest opinions.
