Update: Found @ HA -- Did anyone get an extra Newman envelope?
My lot from the Eric P. Newman Collection Part XI US Coins Signature Auction was supposed to come with an envelope with a notation like "A scarce-to-rare example of the Philip V 8 reales pistareen with cut sides, struck on a screw press". However, it was not shipped to me. If you got it by mistake please contact Heritage. More about this here.
