As far as I know these stamps as imperforated were proof prints and only have a catalog value for unused, these were not meant for usage.
There is no separate catalog value for a single used stamp, so I assume it has the same value as a perf used stamp. The catalog is also saying that it is virtually impossible to tell if a stamp is imperf if it is not at least in the pair format.
Responding to Opa and Smauggie: (1) It seems very possible this stamp is a "real" imperforate, rather than a trimmed perforated stamp. For one thing the paper is different than the perforated 04 stamp, and another is the margins are spacious. (2) Given the 04a stamps were printed as "print proofs," this stamp with a legitimate postmark was in fact postal used; whether it should have seen postal service or not. One would then surmise it was postage used by mistake/error. (3) If we assume that the imperforate 04a stamp was not issued in as great a number as the perforated 04, one would think the value, even if used, would be greater than the perforated version. (4) With that said, I still cannot assign a true value to this stamp.
This is from the 2019 Catalogue, no mention of used.
Are you sure it's not a cut out from postal stationary?
I am sure it is a stamp and not a postal stationary cut-out. The paper is too thin for it to be anything other than a stamp.
Value would be based on whether or not you can obtain a certificate for an imperforate single and/or hammer price at a no reserve auction.
It is a stamp issued in 1875 - perfed similar ones were issued later
It would be considered as a service/official stamp
This series was issued for specific municipal use
The letters approximately translate to "Service matter liable to postage"
They can be found on postal stationary and as singles
They generally sell in the $15-$20 range
Used ones appear to be less common
This is Wurttemberg SC #04a (Official Stamp). My 2014 Scott Catalogue lists a catalogue value ($47.50) only for "MNH Pair." My dilemma is that occasionally Scott's will give a valuation just for a "pair MNH," and not a single stamp, or a used (cancelled) stamp. This is the case with Wurttemberg 04a. How does a collector establish a valuation for the "used" imperforate stamp shown and described? Is there a specialized catalogue that addresses such valuations? Certainly this imperforate stamp has value? Your opinions will be highly appreciated.
