I am new here and let me say I am not a stamp collector. I had a brother who passed away and he collected stamps, specializing in imperfections. I have a lot of his stamps that I do not need. We can talk about that later possibly. But in the world of imperfections, I am pretty stumped on where to go on what I discovered yesterday. I use USPS Priority Mail Regional Rate Box A for 99% of my shipping since January , 2015. I also use USPS Priority Mail Regional Rate Box B on occasion. Yesterday I finished up packing the last of my RRBA and opened a new "case" of 25 USPS Regional Rate Box A that I had ordered last week. Much to my surprise the box changed a bit in construction, but what really surprised me was imprinted on the Regional Rate Box A...
PRIORITY MAIL REGIONAL RATE BOX B POSTAGE REQUIRED
This is obviously a misprint, imperfection, but who has a album large enough to display this flat box. Is this valuable to anyone in the stamp/USPS world Thanks for your time and consideration.\
Joel, I have been collecting for more than 60 years and never heard of anyone collecting boxes like you have mentioned. Yes, they are used to send items through the mails, I guess, but usually we are collecting stamps. Some folks collect metered items or postal stationary, but I am not sure what you have found is collectible even though it is an error. I would like to hear what others think on this topic.
When you use the term "imperfection" that, I don't think, is a philatelic term. We use "errors, freaks, and oddities". What you describe seems to me to be a printing error but not necessarily of philatelic value.
