My name is Claude Ostfeld. I was born in the U.S. and I live in Italy. I run two software companies (one in the U.S. and one in Italy). Since 2016 I resumed stamp collecting which I had been doing when I was a teenager. In the meantime I have collected coins (U.S. Morgan Dollars) under the logo CHO10. 

CHO10IT means that I am operating from Italy. I won't be offering "super" deals but honest genuine well selected nice stamps. 
The areas I follow are Italy and the Italian region and the British Commonwealth. I have complete collections of the entire Italian region and many of the over 100 British Commonwealth countries. I like to have stamps in my collection to compare with those I sell. 
I also enjoy photography and travelling. 

If you are looking for that "particular" stamp (or coin) then send me a message. I have over 400,000 stamps to sell and I am buying constantly. If I don't have it I may be able to find it for you. I generally strive to buy and sell mint stamps (hinged or never hinged). I sometimes sell FDC's, postcards and used stamps.
CHO10IT is a member of IPDA (Internet Philatelic Dealers Association) which guarantees that we adhere to their code of ethics (visible on our site and on
