Some of the Genuine material sold, but there was very little competition and some collectors got some very nice items very cheap. All the Reprints and all the Forged material sold, and there was a lot of competition - the material was sold at three or four times the Start prices.
For the 1920 Chassepot issue - so-called after the Paris printers who produced it - I only sent Reprint material to the auction. The genuine Original stamps do not sell - I have tried and the results are disappointing. It's a bit of a puzzle why buyers prefer the Reprints - including the Makulatur varieties which are common: imperforates, missing centres, inverted centres and so on. You don't usually expect people to prefer Chicory to Coffee, Ersatz to Original.
I remember twenty years ago visiting Dr Ceresa. He produced a box. It had come from a Swiss auction and had originally weighed 12 kilos. Dr Ceresa had taken out what he wanted for reference and offered me the remainders, all of it Chassepot reprint material. I paid a penny a stamp. I think Dr Ceresa made a profit. I made a profit too because I soon found someone who wanted to buy thousands from me, at 3 pennies a stamp. But that was in the days before the Internet.
Nowadays, thanks to the Internet, I can get more than 3 pennies a stamp and for the Makulatur Inverted Centres and Missing Centres, a lot more. Other people have made the same discovery.
Here for example from a current auction in Germany - a leading auction house - is a sheet of the 70 rouble Spinner, imperforate with Inverted Centre. The Start price is 2500 euro. Of course, it's Reprint material - even the small picture allows you to see this but if you want to see more clearly what Reprint material looks like, I show a half sheet of the same Inverted Centre stamp which I happen to have lying around the office. Like the sheet in the auction, my half sheet is gummed:
In contrast, I can only show you a block of 4 of the same variety from the Original printing. Probably nothing bigger than a block of 4 exists. This one came from the Robert H Cunliffe collection of Inverted Centres of the World. I paid over 1000 euros for it. It's most unlikely that I will ever get my money back. But I will cover the loss with profits on the sale of Chicory.
