Helder Silva

Expert Coins

Portugal has an incredibly rich currency history.

Helder Silva

Helder Silva was six years old when his grandfather took him for the first time to a numismatic fair. As director of the numismatic association and one of the largest coin collectors, everyone knew his grandfather. Thus, Helder also became interested and slowly but surely developed a great interest in coins especially from the Middle Ages, on which Helder Silva wrote articles that are posted online. He was soon asked by various magazines to write for them. He also helped the numismatic association with writing and revising their large catalogue (Alberto Gomes).

As one of Portugal's largest currency experts, Helder Silva is an asset to Catawiki. He knows Portugal's rich history of currency through and through. From ancient Rome and Portuguese colonies to the Middle Ages and the Republican period. In addition to evaluating coins and compiling auctions, Helder Silva sees himself primarily as a Catawiki ambassador. He is convinced that Catawiki is the best way to buy and sell coins in Portugal. That's something he loves to show to his big business network, so more and more beautiful coins are finding their way to the auctions.
