1973-1974 Regular Issues – Choose from ALL MNH US Zip and Mail Early Blocks! All Mint Never Hinged (MNH), blocks of 4, unless noted otherwise, e.g., “(6)”. Blocks of 6 will have the “mail early” in the center selvage. You will receive the BEST centering available in stock (F/VF or better), so please don’t judge centering by the photos. Most blocks have staple holes in the selvage, because that’s where the sheets were stapled together when distributed to the post offices. If I have one without staple holes, I’ll send it. The corner/position will be random. Requests for specific positions will be honored if that position is available. The more you buy, the cheaper they get! — — Combined shipping available on stamp purchases. To get combined shipping, please request an adjusted invoice PRIOR TO PAYING (use the “request total” button/link in your cart, or use Buy-it-Now and then “request invoice” prior to paying). Each additional is 25 cents (e.g. 3 auctions would be $1.49 for US shipping, $2.50 outside the US).
