I came across this stamp with a bunch of other Hungary stamps, but I was unable to find out what it was.
I assume it is Hungarian, due to the currency and design and language, but it doesn't say Magyar Kir. Posta or something similar...
I looked for it in my 2017 Scott Classic Specialized Catalogue, but was unable to find it.
A google search yields only a couple eBay
listings for similar looking stamps that seem to be from the same person, as far as I looked, but the listings don't say what kind of stamp it is.
I assume it must me some kind of revenue then? It must be relatively obscure from the lack of internet presence.....
Any insight into its ID and relative value would be appreciated!
