Probably 95%+ of stamps are completely worthless. Certainly the Spanish ones you listed above are. I sold a box of over 100,000 junk stamps including all the ones you posted, for AUD 200 a couple of years ago and was delighted with the price I got.
but i found some of them costs up to â‚¬150 at philasearch auctions.
A Citation is definately needed for this. Just because some idiots may decide to ask stupid prices for exteremly common stamps, I would need to see where they were actually sold at these prices. Your stamps are very, very common and utterly worthless.
please sir tell me what is that 'retail' value. If i have say 10000 stamps dating before 1940's how can i access which one can buy me an ipad or a car or perhaps a house
Retail for what you have scanned is zero, zilch, nothing. If you wish to research your stamps one by one, I suggest that you go to a library, get specialised Catalogues and go for it. Good luck.10,000?
How about 100,000
