fake us mint envelope?

[tbone]

Any way to tell if I've received a fake US Mint proof set envelope?  I ordered an unopened set (1955) from ebay, but the envelope seems a bit too well preserved.  The seller has a very good reputation however.  I can only compare to a few other proof sets I have (1961 and 1957).  The back of the 1955 opens differently than the others (from the short end).  Is this correct?

Thanks in advance for any opinions.

Those look real to me - the 1955 was a different envelope than the later year envelopes.

@Silverhunter Yes, thats the proof mint set.  My concern was that after purchasing, I found a seller on ebay that sold reproduction envelopes that look just like the ones I received (and just like the originals I think, but here I'm a bit of a noob when it comes to these so I could be wrong).  Maybe just being paranoid but figured I'd see what the more experienced here think.

Good to hear, thanks Pampfan.  I ran across a different ebay seller that mentioned that the mint used both envelopes in 1955 (side open and end open).  I guess I have trust issues ;-)

My father told me when I was little

pamp my son, how can I trust you when I don't trust myself.

always good to do your homework.

Thanks again @Pampfan and @Silverhunter , if nobody else thinks they are fake, I'll open it up tomorrow evening and post the contents.  Hopefully I'll have a nice set (hoping for a cameo by shear luck).  If nice I'll probably get them graded.  Its been a fun project despite my doubts on the envelope!

Well, I opened it.  Here's the results:

 Nothing extra special like I was hoping, but I might still get it graded.
