I received the following item today as a holiday gift. https://store.usps.com/store/produc...mps-S_479124
The frame has a mounted block of two Forever stamps. Both are correct side up in the image on the USPS website. In the frame I received, the second stamp in the block (the one of the photo of the moon) is mounted upside down. How often does this happen on these type of items sold by the USPS and do I have any kind of rare, future collectible piece?
