2016 Quilled Paper Heart Variety

Scott 5036 (quilled paper heart) was issued in 2016. Initially it was printed with plate # S11111 (for SSP). Later it was reprinted with plate # B11111 (for BCA). The stamps from the two panes were supposedly identical with only the plate numbers being different. Now fast forward to late 2019. Scott includes a new tagging variety, 5036c, in their 2020 U.S. Specialized Catalogue. The difference … 5036 has overall tagging while 5036c is printed on prephosphored paper. My initial thought was that S11111 was 5036 while B11111 was 5036c. But upon finally perusing the 2020 Scott, I find both plate numbers included under both entries. Is this a typo? Does anyone have any info about 5036 vs 5036c?

Look forward to reading responses.
To my mind, "overall tagging" and "prephosphored Paper" would one of the same thing.
Is there a difference in tag and phosphor?

Unfortunately I don't have the BCA version of this so I can't check it. As such I wasn't aware of the two tagging types for this issue.

Overall and Prephosphored Paper are different types of tagging. The "Tagging Types" tab on Tagging DB provides examples of each type.

I just noticed a typo with one of the examples. The second John Hopkins with the solid green tagging should be: Prephosphored coated paper, with surface tagging

I will work with Don to Fix.

Rod - overall tagging os applied after the printing ink, prephos is on the paper before the ink.

JL - I suspect your guess is correct and that Scott is off.
