Can I Get Some Questions Answered Regarding 2014 Purple Heart

I acquired these stamps on ebay and would like confirmation on the authenticity of them and/or a Scott#. They have no tagging which makes me leary. the Forever USA down the right side is actually red. How do I spot a fake? Any help would be greatly appreciated.

The last three major versions (Scott 4529, 4704 & 5035) of the purple heart have all had a red "FOREVER USA" running vertically down the right side of the stamp.
Your pane is presumably Scott 5035 for two reasons. First of all, the stamp was printed with plate number S111111 (for SSP) ... later it was printed with B111111 (for BCA). The B prefix is unique to 5035. Stamps from the two panes are identical ... only the plate numbers are different. Second, only 5035 has the microprinted USPS to the left of the medal ribbon towards the top of the stamp. This is clearly visible to the naked eye.
The predecessor of this 2015 purple heart is Scott 4704 (dated 2012) & 4704a (dated 2014). 4704 & 5035 look significantly different under short UV even though both are tagged. The older stamp exhibits the common bright yellow-green that we've come to expect. The newer stamp has a much lighter/softer reaction to the UV ... which could be misinterpreted as there being no tagging. This is undoubtedly the result of different tagging chemicals being used. The tagging on 4704 covers the entire pane ... I believe that on 5035 it only covers the stamp area (selvage appears untagged).
If you are concerned about fakes, I suggest you consult a 2019 Scott U.S. Specialized Catalogue. There is a short section towards the end on known postal counterfeits. My 2018 catalogue shows no such counterfeits for any purple heart stamp, but it takes time for new counterfeits to be recognized and subsequently listed.
Added: The presence of the microprinted USPS on your stamps is the one thing that screams GENUINE to me. I know of no postal counterfeits that have successfully mimicked the microprint included on many modern U.S. stamps.

To JLLebbert-I am very grateful you took the time to reply to my post. It puts my mind at ease. I have ordered rolls of stamps on ebay that have been obvious fakes, since there are no pnc #'s, no tagging and sloppy micro-printing. I guess I should stick to the post office, but it is a great place to find stamps to fill those pages in my albums. Hope your holidays are happy and bright!

To Hithere 12 -- I just posted a long piece about this issue. It appears to be a 4704b, as evidenced by the 2014 date. The Forever USA on the 4704 is red and dated 2012, and I know of no reason why it would be different on the 4704b The plate # on my 4704 is C111111, and it is B111111 on your photo, but this does not suggest anything "fake" to me. I see nothing that suggests a forgery in your pane, in fact I'm going to look for another on ebay. Hope this helps you..

To Hithere12 and JLLebbert -- my thanks to you both for the info on the Purple Hearts. JLL is obviously the most experienced collector of the 3 of us. I erred in telling Hithere that the had a 4704b -- I did not see the plate #s. But I thank him for putting me onto ebay. I found my missing 4704b (with Plate # C111111) and got one for $11.00. Also, JLL's advice about using the Scott Specialized U.S. Catalog is spot on -- it contains a wealth of info about almost anything you want to know. JLL: Concerning the imperforate 4704a cut from a press sheet. Was this ever offered for sale as postage by the USPS? If not, perhaps we should consider it a label, not a postage stamp. Also, do you know what the "C" stands for on the plate # for 4704b?

4704a was only available from the Stamp Fulfillment Center in KC and was sold only in press sheets of 3 panes. I believe these "press sheets" were actually removed from even larger press sheets before being sold to the public. At a guess, the original press sheets probably had around 9 panes. These imperforate purple hearts can be used for postage.
The C in the plate number stands for CCL ... just as the S is for SSP (Sennett Security Products) and the B is for BCA (Banknote Corporation of America). I don't recall what CCL is. But, at some point during recent years, the SSP print operation was sold to CCL ... which was then sold again. I think BCA was actually doing the printing for SSP ... and probably continued to do so during the financial maneuvers. In other words, the same physical printer was likely responsible for all three plate numbers, those prefixed S, C or B. But the corporation to whom the printer owed allegiance changed hands more than once.
Added: At the time that I returned to stamp collecting in 2007, there were 3 different print vendors for U.S. stamps ... APU (Ashton Potter), AVR (Avery Dennison) & SSP. Plate number prefixes for the three were P, V & S respectively. In 2012, CCL Label purchased SSP along with its subsidiary BCA. Then, in 2014, CCL acquired AVR's printing. So the S & V prefixes became C. And eventually C became B. Very confusing and I'm sure someone here could fill in the interesting details. For now there are two print vendors ... APU & BCA.

Thanks, JLLebbert. I looked up the link at the end of your post and found a complete discussion of the Purple Heart Issues. I printed out that post for reference. I am interested in Plate #'s, I have just started to collect PNC's And Plate Blocks. I thought my collection of Purple Hearts was complete, but now I see that there are a number of plate #'s that I'll want, and I'm going to consider the imperforate issues because you have assured me that they are postally-valid stamps and not just souvenirs printed for collectors (even they probably were just that!!). And I thought I was over the hump when I found the 4263 pane of 100!! One more thing, how did you develop the link to that specific post?

There is an "Insert Hyperlink" button on the "Format:" line at the top of your post. It's the button to the right of the HR (Horizontal Rule) button. You can then visit the link that you want to include in your post and use your usual "Copy" & "Paste" functions to finish the job. You paste the link between the "url" delimiters that the Insert Hyperlink inserts in your posting.
