Years ago, I inherited these stamps from my mother...they're "G" stamps which back in the 1960s would have been issued to government offices for use on government mail ONLY. They were basically done away with by the 1970s, and all offices told to destroy them. What I was told about 2010 by an exasperated appraiser, was that all sorts of people ended up keeping them instead, with the idea that oh, someday they'd be valuable or collectible, but this has never turned out true. Be clear about it! These can't be used as stamps today, and in collectible terms they are VALUELESS.
But: they're also striking, the effect of a mass of them is fun, and I've used them in the past (example) to cover decoupaged trinket boxes.
Would anyone like them as a craft supply?
This is one of two or three items I'm posting MONDAY AFTERNOON (Sept 11, 2023). I won't be look to see who's interested until WEDNESDAY AFTERNOON (Sept 13, 2023).
Then I'll do my usual: either decide who to offer to, or if there's a lot of interest on an item, I go to a names-in-a-hat exercise.
