I'd noticed that French colonial stamps in general do well at auction, but some areas - eg French Antartcic, which I'd have written off as pure philatelic stuff like the Falklands - do particularly well. Any reason you're aware of?
Yes, I agree, French Antarctic has always done well, French Polynesia especially so, in the auctions I attend.
No reason that I am aware of, Auctions in general in North America
are getting high values at the moment, I just cannot compete with
the exchange rate, and the shipping.
I have not bought anything of note for the past 10 months.
Yesterday I bought 8 pages of mint Belgian semi postals for $9 plus $2.50
shipping (US $)
That was just a fluke, I put in about 5 bids on lots and went to bed.
The only reason I can guess at, is that these types of collection disciplines offer the collector the opportunity to have a "complete" collection within reach,
perhaps the emmissions were also controlled so the numbers were lower,
which always adds value later.
