Do you know the marketplace Ma-Shop ?

The internet connects buyers and sellers like nothing else can. How the average coin collector builds their collection has been changed irrevocably; what the average numismatist collects is changing as well.
Geographical distance is sublimated into shipping fees as the entire world becomes one big coin bazaar.
Five minutes and a smartphone – that’s all a trip to the coin dealer requires in 2016.

CGB specializes in Ancient, foreign World and French coins, not to mention banknotes, medals, tokens and numismatic library supplies (though at the time of writing their inventory on MA Shops does not include books or book supplies). CGB is based in Paris but has a global reach, attending many coin fairs and showsaround the world.
