I believe that is them selling their own stickered inventory. One of the MAC guys was posting in the CU forum about them a while back
I prefer FB for SLQ. wow. I didn't know anyone would stretch the prices that much. MAC sounds worse than Wings, not that I've seen either much out there. If I see either of these stickers on a coins, I will make an effort not to buy them or even ask the price. I see them as just ways or attempts for sellers to capitalize more on their coins
