Not 482A.
Looks like perf 10? What do you get from the perforation gauge? |

The 2 cent Washington stamps can be daunting at first, but a perforation gauge will narrow the field considerably, then any additional steps like watermarking, determining type or printing method should get a unique result. In your case the perforation rate narrows it to only 2 possibilities, differentiated by watermark. Let us know what you conclude. |

What is a 10x12 worth anyway? I don't really collect US stamps and have only some stray ones lying around. |

Checked the stamp smarter site, they don't have images of #423e and b. Checked the perforation again and it seems to be showing 10x12, really confusing. |

Perforations are gauged, not counted. Show us two scans of your stamp (top and side) aligned with your gauge at the point where you think it matches. |

How much is a 10x12 worth? Unknown, since, as of now, only 1 exists. Sky is the limit. |

Perf numbers are based on the distance between perfs, not the number of perfs. Your stamp's perfs are all the same gauge. That is, the distance between perfs is the same on top and on the sides. |

Determining the perf of a stamp is NOT, repeat NOT, counting the number of perfs along the top and then counting the number of perfs along the side. And that statement holds for all stamps the world over. As someone with nearly 500 posts on this forum, I am sure you already know that. After all, it is perhaps the SINGLE MOST BASIC TRAIT OF STAMPS. Having said that:
Simply laying a ruler against your scan, along the top and counting the # of perfs over a given distance, and then measuring the perfs along one side over the same given distance, I can see that the perfs gauge about the same on the top vs. on the side, so I would expect this to be a 10x10 or an 11x11 or a 12x12 stamp. To me, it looks like a 10x10 stamp, but to be sure, you need to compare the perfs with a perf gauge. A perf gauge costs something like $5, or you can search this forum for a printable on-line perf gauge. Get one - it is THE most basic stamp tool (except for tongs, to be honest) you can get. Considering your commitment to the hobby (based on your 485 posts), you should have had a perf gauge and tongs at least 475 posts ago. And a watermark tray about 450 posts ago. |

pennyblackie, Your stamp is perf 10. In that case, it is only one of two possibilities, either a 425 or a 463. The only other thing you need to check to verify which of the two it is, is to water mark it. If it has any part of a single line USPS watermark, then it is a 425, if there is no water mark it is a 463. The Scott CV for a used 425 is 25 cents, and a used 463 is 40 cents. No rarities here. But as others have said, really really really important that you get a perf gauge.  Edit: Added the image above. I used the "Don Denman" photoshop method to compare the horizontal (top) perf to the vertical (left) perf... they are the same size, and from eye, I can tell you this is a perf 10 stamp all around. Find your watermark (or not) and now you'll know 100% what you have. |
