Spanish Civil War (1936-39)

renden ,

I am not a specialist collector of Spain. I, only, can observe the striking differences between the overprint on millersville 's stamp and that depicted in my own 2023 Edifil Cátalogo Unificado, or on the one offered on Ebay.

The seller on Ebay is an established stamp dealer from Barcelona. Neither his listings on Ebay, nor his listings on his own website give me a reason to doubt the stamp he has on offer. However, a stamp with an obscure overprint that he claims is listed by Edifil with a catalogue value of € 475, even at the offered price half the catalogue value shouts 'Can you provide a recent certificate?'

As for the stamp posted by millersville, I think there is good reason to doubt the genuiness of that overprint. Again, I am not an expert. Nor do I have one of these specialised Edifil catalogues. If millersville does not come to the same conclusion - which is understandable -, there is the posibility to have it expertised by one of the established Spanish expertisers.

I think the colour of the overprint itself is not a reason to disqualify the stamp as genuine but the very poor quality, likely, is.

I'm neither a collector nor a specialist on Spanish stamps. But, I happen to have an "Edifil especializado"(1995) catalog on my library. It lists a black overprint variety on the blue 50 cents (Canarias # 29hcc) with a very high quotation (75000 pta = 625 €) for the time. The text looks very much like the one on the stamp for sale and it's different from that of our friend. I guess, it's a forgery. I'm Sorry!

Assuming you do not want to keep it:

It appears to be a forgery. But I wonder if that was what people thought when the black overprint first surfaced. Destroying it would deny specialists to assess whether it is a forgery or an unknown overprint such as a proof. Alternatively, if it is confirmed as a forgery (as it appears to be), destroying it would deny the collecting community the opportunity to use it as a reference of what they should look out for.

If confirmed a forgery, it should, clearly and indelibly,  be marked as such. If so, I do not see the harm in selling it as a forgery.
As long as it is not confirmed, I can also understand that it is sold with the caveat it, likely, is a forgery. Marking it as a possible forgery is an option. I would hesitate to do so indelibly if there is any reasonable doubt.

I did not find in the catalog Scott the 5c stamp and no information about the use of half of Scott # 647.




I saw that the catalogs mention the use of cut stamps - I guess when it was legal.
Is this also the case here?

rednaxela, thank you, but by accessing your link this is what I got

"cut stamps" = Bisects.

The "Pro Sevilla" obligatory charity stamp,  is a consistant date with the covers I have seen of 1937  (Sevilla to Stuttgart)

also Seville to Paris 24th December 1937

Beryllium Guy, a wonderful idea! I'll reach out to the AFRL and see if it is of interest. Thank you as well, salmantino . Chris

 My word!  YES very interesting !

This discipline is possibly the most difficult in all Philately  (Along with Turkish Postmarks)
You need very rare and expensive catalogues

I collect them, but really I only meddle, as they are difficult to source.

You have a fine starter collection. (lots of Pro Sevilla,  the boxed frame cancel is a Seville Registration strike)

cursus   should be able to identify the CATALUNYA examples
