Digipunk, I was the other bidder for that Arrco Service deck (I wanted it to complete my set). I forgot about the auction and lost it, though. I picked up my Service deck for about $16, and I am glad I did.
The Service decks were handed out to soldiers in combat during WWII, that's all I know about it.
sxjy, almost all of the decks are sealed. When I have a lot of duplicates of the sealed decks, I usually open one, so I have an open set of Slims, a Vegas Club, etc.
Levi, I picked up my second Jerry's almost a year ago. I got it about a week after I made my deck collection video for the low price of $200 (Okay, not so low, but it was sealed in perfect condition I couldn't pass that up).
