Hey, they both have the same 2 on the back.
Silver Buyer bought it and decided to flip it as he does with most purchases. I have bought from him before and think he is a top quality guy. I really like how he often says what he paid (I.e., $850 in this case) and always responds to YouTube posts. iMO, he found the coolest bar I have ever seen (I love Fosters Mint) and think he deserves the small amount he made for the find.
