Great Britain Philatelic Society

Hello - I'm new to the group and recently re-started philately after a 50+ year break. I am in a steep learning mode so hopefully this is the right place to post this question.

My current focus is GB 1840-1951, and one of the gaps I have is SG99 (1867 10d red-brown). According to Gibbons this is valued at £55,000 (!) but from what I can tell virtually no one pays Gibbons prices.

What would a more realistic price be for even just a fair quality item? Note, I am not even remotely close to affording the Gibbons price so this gap may have to stay as a gap.

Thank you for any guidance you can offer.

Hi NBHRH2
The stamp you are looking for is available for purchase. The web site is
www.mercator.direct. The price has been reduced twice, eventually to £2,100.
I do not know the seller or agent. I also don't know why there appears to be no bids
Please be wary because it is a very rare stamp, only eleven known copies used.I don't know how many have survived
If this is genuine, why hasn't there been any bids, Especially at a greatly reduced price?

Hi AB1961,
Thank you very much! Is it fair to assume that the watermark would be the best guarantee of authenticity or are there other indicators to look for you know of?

Hi NBH RH2
I agree that the correct watermark is helpful but not absolute proof of authenticity. The GBPS surface printed consultant may know more . There is a managing director of a auction house who is a provenance researcher but I don't know if I'm allowed to provide you with his contact details. I could make more enquiries.
I would have thought that a stamp of this rarity should have a checkable history . I would want to know it's pedigree. I would also expect many bidders and watchers.

Hi AB1961,

Again, thank you very much for the guidance. Much appreciated.
